When successful Spanish research scientist Diego (Adria Collado) sees his spitting image get killed in a Buenos Aires car accident, he becomes convinced that the man was his long lost twin brother and sets out on a desperate search for his biological parents, in the process becoming embroiled in a vast conspiracy involving cloning and violent Russian heavies. Diego and his best friend Martin (Alfonso Lara) are watching television when they see a man who bears a striking resemblance to Diego get killed on television. Diego has long been the victim of repeated déjà vu, and now he's beginning to wonder if there may be a rational explanation for his many strange experiences. When Diego discovers that he was adopted as a young boy, he leaves his wife Susan (Lucia Jiminez) to travel to Argentina and get some answers. The situation grows increasingly complex when Diego comes into contact with the dead man's parents, who claim that their son was adopted as well. Ageing alcoholic Malcolm (Jose Maria Pau) may have just the answers they are searching for, but when he questions Diego about his wife Susan, Diego wonders how a the man could even know of his wife's existence. Meanwhile, back in Spain, things get complicated when Susan is contacted by a man named John (Andrew Bicknell), and becomes the unwitting target of Russian thugs-for-hire Djanov (Bruno Squarcia) and Cherkasov (Manuel Tomas del Estal Castano).
