What’s the size of happiness? Twenty centimetres. Transsexual Marieta, born as Adolfo, wants to get rid of both that name and of the other reminder of her maleness – the 20 centimetres she hides under her skirt. Marieta suffers from narcolepsy; thus she can’t get a decent job and works the streets to earn the money for her surgery. After one such narcoleptic episode, in which she dreams she is a star in a lavish musical, she awakes while being rescued by a rugged hunk Raul. He is into her body, particularly her 20 centimeters. But Marieta faces a big dilemma: Should she accomplish her plans for surgery or live happily forever after with Raul?
