Grave Decisions (2006)

11-year-old Sebastian (Markus Krojer) thinks you can never be too young to be a murderer. He's convinced that he killed his mother on the day he was born and is certain he's already been condemned to purgatory. Deciding he might be able to knock off a few years of his sentence by doing good deeds, Sebastian sets out to find a wife for his father Lorenz (Fritz Karl). When Lorenz and Sebastian's schoolteacher Veronika (Jule Ronstedt) fall madly in love with each other, it seems the heavens must be smiling. There's just one hitch: Veronika is married.
