Pepe Moco, a mentally handicapped boy, who makes an advert for one of the presidential candidates who promises to organise the first World Cup in Guatemala. Beto is a kid who scales a town drawn in chalk, venting his spleen on its walls, threatening passersby with balls. The two of them soon become very close evoking the past and present of a country that does harm.

Don Alfonso plays marimbas, the traditional Guatemalan instrument. Facing extortion and without work due to the population's lack of interest for his instrument, he seeks refuge with his godson Chiquilín. Blacko is a pioneer of the Heavy Metal Guatemalan underground stage. He is also a doctor in the public hospital but nobody wants to be treated by him because of his long hair and his tattoos. Chiquilín makes connections for Don Alfonso and Blacko to combine their talents and create a brand new band called Marimbas from Hell.

Hernandez had already made films in Guatemala and Mexico and this time found inspiring locations, unusual atmosphere and enthusiastic young people in Costa Rica. In this consciously unpolished film, the rebellious girls Sole and Ana open the trunk of a car in grandma’s garden and find something they’d rather immediately forget.
