Johannes devises a plan to get Marion back – but when things goes awry, it turns out she's actually just as moved by his openness towards Sascha.

Johannes, Sascha, and Marion are having a great time together at her apartment until her new boyfriend shows up unexpectedly – with plans to propose to her.

Dirk tries to console and help a homeless man named Kutte whom he has known for 15 years. While on patrol, Ben and Katja come across a young woman buckled over in severe pain.

While Johannes tries to win Marion back, Sascha's parents continue fighting. He overhears his mother accusing his father of cheating – and his father denying it.

The young mother cannot be found anywhere, and we learn that she is in high school and still lives at home. Kutte is found camped out in front of the precinct, despite Dirk having secured him a place to sleep at the night shelter.

Marion and Johannes share a bottle of wine together, and Marion admits that she has feelings for him and sometimes wishes they had never split up. But their moment is interrupted when Sascha appears and has a terrible accident.
