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 and 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. The film is told in flashbacks from the point of view of Antonio, a young man from the upper class of Medellín. While at a Medellín disco one night, both he and his best friend, Emilio, simultaneously lay eyes upon the beautiful Rosario. Emilio pursues her and begins an affair with her, despite knowing that she is involved with
drug cartel leaders, and despite getting entangled in her violent life. However, Emilio's family rejects the relationship, which crushes Emilio. Antonio continues his own platonic relationship with Rosario as her confidante. When Rosario's brother, Johnefe, with whom Rosario lives, is killed, Antonio and Rosario grow closer. All along, Rosario starts falling in a spiral of drugs and violence, dragging both Emilio and Antonio with her. Rosario, who often kisses the men she then kills, is a marked woman, and eventually meets her comeuppance. Antonio takes her to the emergency room, from where he relates her story. ==Cast==
