Christmas has come again and the gang are throwing a party. At a ice rink, Markus tells his dad the only thing he wants for Christmas is for his family to be all together. When his dad leaves, Tommy switches places with Markus while he goes to visit his mother. While Markus is gone, Tommy is kidnapped.
Moser continues with his investigation. But things get worse when the kidnappers realise their mistake and track down Markus. Instead of one child missing, Moser must now find both Tommy and Markus before anyone else gets hurt.
