Boxer is the king of the prison. Nothing happens without him in "his" prison, and if he has to, he will even knock out a much younger inmate - at over 80 years of age, mind you.

Boxer is to be transferred to a prison especially for senior citizens - the idea alone makes the sprightly prison veteran shudder. But then his buddy Henne tells him that he has been looking for Boxer's great love Kathrin, and what's more: he has learned that Kathrin has a daughter - and she looks remarkably like Boxer...
