The simple story has the pair coming to the rescue of peace-loving Mormons when land-hungry Major Harriman sends his bullies to harass them into giving up their fertile valley. Trinity and Bambino manage to save the Mormons and send the bad guys packing with slapstick humor instead of excessive violence, saving the day.

The two brothers Trinity and Bambino are exchanged by two federal agents and take advantage of the situation to steal a huge booty hidden in a monastery by a gang of outlaws.

The Trinity legend continues when the sons of Trinity and Bambino head out on the road to continue the legendary hijinks of their fathers.
