The talented young entrepreneur Finn Sieveking has to cope with the death of his mother Maria, who was always at his side in the management of the traditional Hamburg family business. Out of nowhere the adventurer Jonathan Clark appears, who introduces himself as his biological father. Finn has to cooperate with him unwillingly, because Maria has bequeathed both of them half of their business shares. Only gradually does Finn begin to understand what his clever mother intended.
