Celso, a dancer and accordion player among the Soldiers of the Virgin, dreams of being a musician despite a bleak future. Desperate, he sells his soul to a cumbia-loving hitman, the Devil. As long as Celso lives, he will be a musician, but his music will be born from horror. This deal grants him power but also fear of losing it, as he sings of pain and betrayal. The horror becomes his fate, while cumbia resonates in the neighbourhood, and God and the Devil dance with him.
