Vítor, whose mother left the city leaving him to his fate, and Albertano, who is looking for a new home, come by chance to Doña Cuquita's house.

Vítor and Albertano manage to get work as drivers in a microbuses base, but their irresponsibility is going to be very expensive.

In their attempt to get jobs, Vítor and Albertano think they are clowns for children's parties, but this fun work will not be as easy as they thought.

When listening to the serenade of the neighbor, Albertano and Vitor realize what a mariachi wins, so they decide to create theirs to pay their debts.

Thanks to a stroke of luck, Albertano leaves out of combat the toughest guy in the colony, an opportunity that Victor takes to make him the new promise of national boxing and thus make a lot of money.
