Sonia’s life was perfect at first. Her theatre career is improving and Óscar the man who is having an affair with her promises her to leave his wife for her soon. But suddenly her life descends into a downward spiral of terror when she receives photos of them two being together. This is the trademark of a serial killer who already has killed four women and now Sonia is the next target.
