After 15 years as coach of a middle-class ice hockey team in Canada, Harry Zoppke has served his purpose. Without a job and without a family, he returns to his hometown of Freiburg. While looking for work at his old club, the EHC Freiburg, he meets Benny, whom he once coached. Benny has come a long way as a joke item manufacturer. But Benny is always plagued by the uncertainty about the identity of his father. When Benny discovers that Harry is left-handed like him and has the same allergies, he is convinced that Harry must be the long-awaited biological father. Benny, in turn, is completely taken aback and ultimately misses the right moment to explain the misunderstanding to Benny. Instead, Harry soon enjoys having a son and no longer being alone. Benny now finally has the father he always wanted.
