Joy of Fatherhood

Years after he gave his sperm away, Felix (Matthias Schweighöfer) learns he can no longer father a child himself, and somewhere out there a woman may be raising the only one he'll ever have. He sets out to find her, with Henne (Friedrich Mücke) and Ralph (Tom Beck) tagging along as his friends. Schweighöfer, who also directed, plays Felix as a man standing in a stranger's doorway with his hands in his pockets.
