In 90's Habana, a nurse and a home builder, hopelessly in love, live happily married. A circumstantial fact of her past life will put their feelings to test and undermine the most elemental principles.

Mavis is a Cuban transsexual who, 20 years after her sex change operation, questions the way in which she has developed her femininity based on the stereotypes and prejudice of the male-dominated, patriarchal and hegemonic society she lives in. An intimate trip within her leads the spectator to question the sex-gender distinction.
