It tells the origins of the Spanish rock music group Men G, where the group members play themselves in the film. It is based on the song "Give me back to my girl", based on a fact that happened in the life of David with an ex-girlfriend named Macu. The story, except the fight with the Yellow Fever, the pica pica powder, the monkey and small details added to give it more dramatization, is very real, both emotionally and in the musical.
