Despite being married and having everything he needs to be happy, the father of two is secretly depressed with his life--a far cry from the profession of a photographer that he dreamed of in his youth. But destiny leads him to an organized disappearance on discovering that his wife is cheating on him. He accidentally kills her lover who, as luck would have it, is a photographer. He steals her lover's identity and starts a new life but soon realizes that completely erasing the past won't be that easy.
