Fremdgehen (2010)

The married lawyer Nikolas Merz is having an affair with Meryem, a Turkish woman who works as a cleaner at his law firm. One day, he leaves his wife, Lilith, because he wants to move in with Meryem. But Meryem is afraid that, in that event, her husband Rohad would abduct their son, Baran, and take him to Turkey, so she does not want to leave him. However, after Rohad discovers the affair and threatens Nikolas, she does leave him. When Meryem suffers a miscarriage and has to go to the hospital, she cannot reach Nikolas and calls Rohad for help. This is how the two men meet at the clinic. On the way back, Rohad pulls over, drags Nikolas out of the car, and knocks him to the ground. Nikolas then beats Rohad to death with a stone he has picked up from the ground. Nikolas reports the incident to the police and waits at home with Lilith, to whom he has grown close again in the meantime, for his arrest. As they wait, they both dream of taking a trip. Meanwhile, the police arrive.
