Single mother Sandra Lindt lives with her son Dennis in a Hamburg old-apartment. A company plans to enlarge their area. Therefore they employ the comely lawyer Siegfried Hübner to banish the residents from there. Sandra also belongs to it. But Sandra doesn't want to move, because she has a problem: She is a messy-person. The apartment looks like a maze of waste. Even her son Dennis isn't allowed to invite some friends for his birthday party. Nevertheless Siegfried tries to conquer Sandra's heart, so that Sandra will change her mind about her messy-problem and then the move.—RSaVLSG
