Bulma, Gohan, and Krillin have been taken captive by an army of children! These young soliders believe that Gohan and his friends are allies of Frieza, the evil warlord who destroyed their home planet. Now, with time running out, the Z-gang must find a way to convince the kids of their innocence.

Bulma, Gohan, and Krillin make a rough landing on what they believe to be Planet Namek, but when their ship falls off a liff, it seems their journey will come to an untimely end Luckily for or heroes, two kind Namekians appear in the nick of time and pull them to safety. Offering to help them in their quest, the Namekian named Raiti leads their gang on a search for the Dragon Balls.

On Planet Namek, Gohan, Krillin, and Bulma continue their search for the Dragon Balls with the help of their new friend Zaacro. Standing between them and their goal, however, is one mean giant! Meanwhile, back on Earth, Goku has escaped from the hospital to begin training for his upcoming re-match with Vegeta.

As Bulma, Krillin, and Gohan close in on the last of the Dragon Balls, they uncover a shocking secret about their Namekian friends. And while Goku works to build up his strength back on Earth, far across the galaxy, Vegeta has begun making plans of his own. The Saiyan prince's sights are set on one thing - revenge.

After fleeing from the wicked aliens, Bulma, Krillin and Gohan arrive on the planet Namek. But they are not alone. Vegeta is right behind in his own space pod. To make matters worse, the dreaded Frieza is already on the planet, and he has three of the Dragon Balls!

While Bulma, Krillin and Gohan discuss what to do next, Frieza sends two soldiers to inflitrate their ship. But Krillin and Gohan's combined might is too much for them to handle, and they are easily defeated. Meanwhile, on another part of the planet, Vegeta defeats his longtime enemy, Cui.

Back on Earth, Gokus is sufferning from an illness, but a magic Senzu bean offers a full recover. When Goku hears about the trouble on Namek, he jumps into his old spaceship, rebuilt by Bulma's father Dr. Briefs. On Namek, Krillin and Gohan witness Frieza's power and learn that he has collected four Dragon Balls!

Namekian warriors fall under attack from Frieza's forces as the evil villain continues his earch for the fifth Dragon Ball. Dodoria, Frieza's red-faced henchman, leads the assault. Meanwhile, Goku continues his voyage to Namek in his space pod, where he finds plento of time to train for the coming battle.

Unable to stand by and watch the torture any longer, Gohan leaps out of hiding to rescue a Namekian boy from the clutches of Frieza's evil henchmen. Now Gohan and Krillin have an even bigger problem on their hands - Dodoria is chasing them, and he won't stop until he has his revenge!

Vegeta catches Dodoria in his search for Gohan and Krillin, and attacks. In an attempt to save his life, Dodoria reveals that Frieza was responsible for the destructino of the Saiyan home planet (also called Vegeta). Vegeta destroys Dodoria in return, and begins his own quest for the Dragon Balls. Meanwhile, Gohan and Krillin reunite with Bulma and learn that Goku will soon arrive on Namek.

Goku runs into trouble when his space pod begins to drift towards a star. Goku has to think fast in order to avoid getting bumped up. Back on Namek, Vegeta beats Frieza to the sixth Dragon Ball and hides it in a lake.

After saving Dende, Gohan and Krillin feel a large Ki and recognize it as belonging to Vegeta, who is attacking a village to obtain the Dragon Ball there. Dende learns why the others have come all the way from Earth, and begs them to help save his people. Elsewhere, Goku continues his training on his spaceship. King Kai speaks to Goku's mind, saying that Piccolo and the other late warriors have arrived on Kai's World asking for the same training Kai gave Goku.

On Kai's World, Tien, Chiatzu, Yamcha and Piccolo arrive and begin their training after Piccolo inadvertently tells a joke. Meanwhile, on Planet Namek, Zarbon and Vegeta find each other and begin their battle.

Vegeta challenges Frieza's green-haired assistant Zarbon to a fight. Vegeta appears to gain the upper hand, but Zarbon transforms into a powerful monster and defeats the Saiyan. Meanwhile, goku continues his space pod training and Krillin and Dende remain on their quest for Guru.

Krillin and Dende finally reach Guru's home, where the eldest Namek explains the history of the Dragon Balls as well as Piccolo's unusual origin. Sensing Krillin's innate goodness, Guru awakens Krillin's latent powers and gives him the last Dragon Ball.

Yamcha, Tien and Chiaotzu continue their training on Kai's world and sturggle with their assignements against Bubbles and Gregory. However, Piccolo finds Kai's methods foolish and refuses to participate, but finally joins in sparring against the other three. Meanwhile, Zarbon finds an unconscious Vegeta and brings him back to Frieza.

On Namek, Vegeta finally recovers from his battle with Zarbon, and escapse from Frieza's base with all five Dragon Balls. He discovers that Krillin has the seventh Dragon Ball and goes after it, with Zarbon in hot pursuit. Meanwhile, Goku's spaceship begins passing through a violent magnetic storm.

Goku's space pod encounters a magnetic storb, casuing the gravity machine to go haywire. Goku barely survives the most intense gravity he has every experinenced: 100G. On Namek, Krillin reunintes with Bulma and is almost immediately confronted by Vegeta and Zarbon, who begin to fight over Krilin's Dragon Ball.

Vegeta defeats Zarbon and gains what he thinks to be the last Dragon Ball. But on his way to summon the Eternal Dragon, he runs into Gohan, who (unbeknowst to Vegeta) is reutrning with the seventh Dragon Ball. Meanwhile, a furious Frieza sends for the Ginyu Force to help him recover the Dragon Balls.

Bulma has a dream about Vegeta killing her and stealing the Dragon Ball, but she falls out of her chair and wakes up. Elsewhere, Vegeta strategizes about how to get the seventh Dragon Ball, when several violent, quake-causing energy waves flash by. Bulma tries to hold on to the canyon wall, but the Dragon Ball rolls away and into the lake. She doesn't want to get wet, so she tries to fish it back in with a stick, but ends up pushing it farther into the water. She says that she'll wait for Krillin to get it when he comes back, but the ball rolls further down into the cavernous lake. Bulma pops open a submarine capsule and goes to retrieve it. She runs into a giant water dinosaur. She sees that the Dragon Ball is stuck in the scales on its back, so she fires torpedoes at it. It turns around swims off, dropping the Dragon Ball. In Space, Goku continues to wear himself out training at 100 G-Force.

Bulma screams to be let down, and reminisces on her troublesome life. She bites the soldier holding her, and she drops him. They catch her and land in a clearing. Bulma tries to escape but her efforts are fruitless. She eavesdrops on their conversation and finds out that they don't know about the Dragon Balls, so she explains to them how the wish could make them stronger than even Frieza. They like the idea of boundless strength and insist that she show them where the other balls are. In Space, Goku uses to Kaio-ken to form a energy ball and throws it into the gravitational pull of the gravity machine, causing it to cycle around the room. Goku then gathers energy for a Kamehameha and fires it at the other energy ball. Instead of them connecting, they overlap and hit Goku, one on the back and one on the chest. He endures the hit as if it were nothing.

Gohan and Krillin continue to fly towards Guru's. Krillin says that when Gohan's latent power is released, he may not even be able to challenge Vegeta, but he should be able to buy Goku more time to arrive. In Space, Goku finishes his training and returns the gravity to normal. Even he is impressed with how far he'd come. He takes a bath, drinks a sports drink, and rests the final leg of his voyage to Planet Namek. As Goku lay resting in his bed, even he does not know that he has crossed the threshold of power than any Saiyans could attain. On Namek, Gohan and Krillin finally near Guru's home, but before they get there, they sense Vegeta's energy at a very short distance away from them. Krillin stays behind and tells Gohan to go on to Guru's.

Frieza addresses the Ginyu force with their mission: find the Dragon Balls and capture Vegeta. The Ginyu Force check their scouters and track Vegeta, along with two other sources of high energy Frieza tells them that it is just two weaklings from Earth. Guldo has a flashback to when Vegeta insulted him on one of Frieza's planets. He almost attacked Vegeta, but Frieza blasted him from behind and stopped him from doing it. Guldo begins to taste revenge, as the Ginyu force perform a routine warm-up and take off to fulfill their mission.

Gohan and Krillin battle Guldo, the smallest member of the Ginyu Force. The four-eyed Guldo may be small, but he uses his powerful time-freezing attacks to wear down our heroes. Fortunately, Vegeta is now on the side of the good guys, and he steps in to protect Gohan and Krillin.

Recoome is the next Ginyu fighter to attack, and he has his sights set on Vegeta. Vegeta gives it all he's got, but he is no match for Recoome. Now it is time for Krillin and Gohan to return the favor, stepping in to help Vegeta. But where is Goku?

Captain Ginyu hands the seven Dragon Balls to Frieza, but he is unable to summon the Eternal Dragon. He leaves to find Guru in order to discover the problem. Meanwhile, Recoome is defeating our heroes, but Goku's arrival on Namek turns the tide.

Goku finally emerges out of the Space pod and tries to detect the life force of both Krillin and Gohan. Goku finds it very difficult because their powers are deceased. After Goku finds them he takes to the sky and is there in an instant.

After finishing off Recoome, Goku is now up to the last members of the ginyus Burter and Jeice. After telling them to return home Jeice and Burter take to the skies and launch an attack on Goku called the Crusher ball; which Goku launches it away.

Burter and Jeice are now stuck with Goku to fight, as Recoome is down. After there Crusher ball move does not work they have to find a way to get Goku but nothing works and are in trouble for neither of them cant land a punch. How will they be able to stop the saiyan warrior!

Vegeta leaves Goku behind to get the Dragon Balls for himself, leaving Goku to face Captain Ginyu alone, while Krillin and Gohan get the radar to get the Dragon Balls. However, time is of the essence as Frieza gets closer to Guru; and Goku has a few surprises up his sleeve for Captain Ginyu.

It seems that Goku is more powerful than Ginyu, but the captain won't give up so easily. Meanwhile, Guru sends Dende off to tell Krillin and the others the password with his potential unlocked as Frieza arrives to get the password. Can Nail hold Frieza off until the dragon is summoned?

Nail gives it everything he's got against Frieza as Dende flies to the others, but Nail can't hold out much longer. Meanwhile, Gohan and Krillin get the dragon radar and head towards Frieza's spaceship, while Captain Ginyu has a surprise of his own for Goku.

Krillin and Gohan arrive at Frieza's spaceship and found the Dragon Balls, unaware that Vegeta is not far away. As the two heroes figure out what the password is, Jeice and Captain Ginyu, in Goku's body, arrive as well. The cleverly disguised Ginyu tries to trick Krillin into believing that he is who he appears to be, but Gohan can see past his lies and knows the truth as Goku arrives in Ginyu's broken body. Can our heroes beat Ginyu with Goku's power?

Ginyu tries to power up with Goku's body, but he keeps getting weaker by not using mind and body. As Krillin and Gohan fight Ginyu, Vegeta fights Jeice and it seems the Saiyan Prince has gotten stronger too. Has he become a Super Saiyan as well?

Realizing that he's no match for Vegeta, Ginyu tries to use his body switch move on the Saiyan Prince, but Goku is able block the attack and got his body back. Back in his broken body, Captain Ginyu tries his trick again to survive in Vegeta's body. Luckily, Goku is able to throw a frog to intercept the transfer. With the Ginyu Force defeated, Goku recovers in the isolation chamber in Frieza's spaceship while everyone else prepares for a battle with Frieza.
