The sizzling summer of love and drama is officially underway! Host Arielle Vandenberg welcomes 10 sexy single Islanders to their beautiful beachside villa and it doesn't take long for them to couple up, but when a surprise Islander moves in, ready to turn heads, someone might go home before they have time to unpack.

After Kyra chooses the guy she wants to couple up with, one female Islander is left riding solo while some of the other pairs start to rethink their choices.

When two new male Islanders (Dylan and Cormac) walk into the Villa, the girls see potential options while the guys smell competition.

Dylan spends some alone time with Mallory, while Cormac attempts to steal Elizabeth from Zac. Plus, the male Islanders must overcome an assault obstacle course before everyone braces for the season's first recoupling ceremony.

Yamen starts to build a deeper connection with Alana, while Caro gets to know Cormac a little better. Meanwhile, all the Islanders band together for Weston's rootin'-tootin' birthday, which is upstaged by the arrival of two new female Islanders.

The two new girls don't get the warmest reception from some of the female Islanders, but the boys more than make up for the chilly reception. Meanwhile, after spending quality time with Christen, Cashel and Yamen each start to second-guess their current romantic situations.

Yamen and Weston cuddle up to Christen and Katrina, respectively, while Alana and Mallory spend an unromantic night in the Hideaway suite together. Then, after a comical competition empowers all the girls, each boy takes ultimate control at a recoupling ceremony that sends two Islanders packing.

Winston arrives at the Villa looking for love and ready to abandon his single status. Plus, a few couples get real about their relationships while an R-rated challenge raises everyone's heart rates.

Caro starts to fall for Cormac, but she questions whether the feelings are mutual. At the same time, Zac and Elizabeth can't stop gushing over each other, which is fitting when the Islanders compete in a stomach-churning food-themed challenge. Finally, Arielle appears in the Villa for an unexpected dumping.

After saying goodbye to Christen and Cormac, Kyra cools things off with Cashel and Zac asks Elizabeth to be his girlfriend. Then, three new girls and three new boys enter the Villa, and quickly start to drive a wedge between a few of the couples.

Not everyone in the Villa is excited to welcome three new girls and three new boys into their abode, but nerves seem to settle after all the Islanders play a game that results in truths and tonsil hockey. Meanwhile, Weston can't deny his attraction to Kelsey, while Eric makes a beeline for Caro...and Kyra.

Eric's ego continues to polarize the Villa, but his self-confidence is having a positive impact on Kyra, who still can't decide if she's totally done with Cashel. Plus, Elizabeth and Zac FINALLY get some well-deserved time away from the other Islanders. Unfortunately, their post-date euphoria is interrupted when Arielle shows up to announce an unexpected dumping.

It's time to recouple and the results lead to one boy being dumped from the island. Meanwhile, the Islanders find out what America thinks about them and the sentiments aren't all positive. Luckily, each couple takes the critique in stone-cold stride. (Yeah, right).

Yamen grows increasingly frustrated when some of the Islanders accuse him of being a player, while Weston and Kelsey embark on a romantic (and restorative) date that brings them closer together. Then, an unexpected dumping leaves the entire Villa shook.

The Villa deals with the fallout from Katrina and Cashel's recent dumping, which provokes Kyra to push Eric away. Luckily, the arrival of three new Islanders lifts everyone's spirits---that is, until one female bombshell threatens to break up more than a few couples.

It doesn't take long for Eric to rebound from Kyra, but he's not the only one with a crush on new girl Emily. Meanwhile, Caro starts to vibe with Ray, but can't deny her attraction to new boy Anton. Finally, Weston appeared to find his dream girl when Kelsey entered the Villa, but looks can be deceiving.

A savage recoupling ceremony sends three Islanders packing and the remaining pairs reeling. Plus, Ray and Caro check into the Hideaway for a passionate evening alone, but it's Weston and Emily's steamy PDA session that has the whole Villa buzzing.

Weston looks like Emily's dream guy until the girls tell her about the good old boy's less attractive qualities. Feeling duped, Emily confronts her new boo, who doesn't take kindly to his character being questioned and does whatever he can to save face. But will it be enough to stay in the Villa with Emily?

As we inch closer to the finale, the Islanders say goodbye to yet another couple before embarking on their craziest challenge yet-parenting! Lucky for Caro, her knack for baby talk with Ray helps them win a gold star for guardianship. Unfortunately, jubilation is fleeting because another dumping is right around the corner.

The Villa gets two more vacancies when America chooses which four couples make it to the finale. Meanwhile, Kyra gets a little help from cupid (or the production team) when she unexpectedly reunites with her true love. Plus, two couples set out on their final dates and both end in tears--but, like, in a good way.

The last two couples go on their final dates before a surprise visit from their nearest and dearest. While some parents can't wait to set a wedding date for the dreamy duos, others are a lot more skeptical that these relationships are built to last. With only one episode left, who will America vote as the winning couple?

The final four couples wake up to a beautiful brunch, which gives everyone time to reminisce about their time in the Villa. Then, the girls go dress shopping and the boys start penning their speeches. Finally, after each twosome delivers heartfelt declarations of love, Arielle makes one last appearance to announce who America voted as the winning couple.
