Kathy lives in a town on the Chilean coast with her mother and brother. Notable about her life is the absence of her father, who is in prison doing time for robbery. Also noteworthy to Kathy are the daily struggles and difficulties in her life. At her high school she meets Chemo - handsome and sensitive - and together they embark on an intense relationship. First love and first physical encounter happen for Kathy as her family falls apart, and as she is faced with a sudden growing loneliness. Director Gonzalo Justiniano was inspired to the story in B-Happy by a young waitress he met in northern Chile. In her, Justiniano encountered someone used to a rough life - one that the director found astonishing in its difficulty, yet seemed so completely normal to her. He was also interested in putting an image of one of the multitude strong anonymous youth of Chile on screen- something that is rare in South American cinema.
