In the midst of protests of Mexico 68, two teenagers, Felix (Christian Vazquez) and Ana Maria (Cassandra Ciangherotti), from different social classes fall in love. The story begins with increasing repression of the student movement by the government of Gustavo Diaz Ordaz in the months prior to the Tlatelolco massacre of October 2, 1968. The relationship of Ana Maria and Felix takes place in the context of repression, forced disappearances, and an attempt to obscure the social protest.
