Lupe is a Puertorican-American living in late 1970’s New York City. Her handwritten journal guides us through her experiences in 1978 as she meets Debbie, another runaway kid, in the cell of a juvenile detention centre. Debbie introduces Lupe to the punk scene of the Bowery and exposes her to the secret worlds coexisting in the Lower East Side in the late 1970’s. Helped by legendary musician Elda Stiletto, they form a punk band while escaping the grip of the Satan Sinners gang, chasing after them for stealing a member’s bike.
