A petty criminal (Ismael), shoots and kills a painting restorer during a bungled burglary, and shoots her daughter as well. Twenty years later, and the daughter has been left mute with the mental age of a child, spending most of her time in a mental home. A chance meeting between the girl and Ismael, who now works in a bar, leads Ismael to think that she still might be able to recognise him, and turn him in to the police. Ismael kidnaps the girl so he can determine if she recognises him, but is unable to kill her, however, and instead asks the mental home for a ransom for her return. Whilst a prisoner, though, the girl and Ismael grow closer but Ismael's girlfriend doesn't like this turn of events and pretty soon tensions start to fray.
