A nurse Samuel Perrier learnt what it was to be at the wrong time in the wrong place. Taken his pregnant wife, Nadia, to the hospital Samuel practically disturbed the attempt to kill a famous bear hunter Hugo who got in the same hospital. As soon as Samuel put an oxygen mask on Hugo, which was torn by an assassin, he unwittingly became a member of a sinister plan conceived by bandits and rogue cops. In this ingenious scheme each has his own role to play. Perrier was assigned to become a victim, but Samuel does not want to play it.
