Injustice and the demands of the world can cause stress for many people. Some of them, however, explode. This includes a waitress serving a grouchy loan shark, an altercation between two motorists, an ill-fated wedding reception, and a wealthy businessman who tries to buy his family out of trouble.

El Mono, Maikel, Balde, Mafia, Mariano and Memo are six bricklayers who decide to appear in a beat band contest to fulfill their dream: dedicate themselves to music and barbecue. On the way to the contest, in which they are divided to fulfill different objectives (gather instruments, beat clothes, groupies, etc.), they will be caught in the most hilarious adventures in which they will be helped by strange characters.
