Redheaded twins Armando and Beatriz always dreamed of being firefighters but during a rainy, uneventful winter they find themselves spending less time putting out infernos than they do helping neighbors who've locked themselves out of their apartments. This is how Armando meets a pretty young woman with whom he begins a tentative courtship. But soon a rift grows between the siblings and, spurred by Armando's exaggerated stories about his nascent relationship, Beatriz begins experiencing aural hallucinations that can only be remedied through music and, finally, the love of a stranger.
