Jonas is a crime photographer, a family man, and a generally beleaguered resident of suburban malaise until he's involved in a car accident that leaves a stranger, Julia, unconscious in the hospital. Curiosity compels Jonas to visit her, but when Julia's family mistakes him for her boyfriend, Sebastian (whom they've never met), Jonas readily steps into the role. His pretense would be short lived, but Julia awakens with amnesia and, enlivened by the new identity he's inherited, Jonas maintains the deception. Of course, memories return. And so do boyfriends.
