The movie, based on a novel by Jorge Franco, deals with the life of a beautiful woman involved with the subculture of sicarios, the motorcycle-riding hitmen of the slums of Medellín, Colombia, in the late 1980s-early 1990s. Rosario, a dangerous woman who was molested and raped as a child, and now claiming to be owned by no man, lives a life on the edge while trying to come to terms with her past and the men in her life, not making the best choices along the way.
