Rosario Tijeras has been abused by men all her life, initially by her stepfather. Years later, she works as a paid assassin, seducing men and killing them when they least expect it. She meets Emilio, a wealthy womanizer, and his best friend, Antonio, at a nightclub, and starts an affair with Emilio despite Antonio's growing feelings for her. But circumstances bring her closer to Antonio, until her past catches up with her in a devastating way.
Cheating Notes
Rosario hooks up with Emilio and they have sex several times in the movie, but while being with him, she fucks an important person in the underworld (13:07), not necessarily as a hooker but as a gift by her thug brother to the said guy. She also stays with another rich and important person for a while, but we don't see her have sex with him. She also makes out with at least two targets before shooting them.
When Emilio introduces Antonio, his best friend, to Rosario in a club, she passes a pill into Antonio's mouth using her tongue in front of Emilio (16:40). I dunno, maybe this is just a normal Colombian thing to do to your new boyfriend's friend, so no big deal here.
At 1:39:53, Antonio gets a chance to fuck Rosario after she and Emilio have a fight and Emilio leaves the house.
