Unit One is called to Aabenrรฅ when parts of a woman body is found in Knapsรธ. As Unit One checks the German Missing List, a witness tells of a silver Audi from where a man tossed a trashbag into the harbour, and of a burning container filled with personal files on a Doris Frรถse. The owner of the silver Audi, Manfred Schlosser, lacks any information. A summerhouse owner contacts them and tells that the sheets and beddings have been replaced and the floor scrubbed very thoroughly. Blood samples confirms the victim to be Doris Frรถse, but the name of the man who borrowed the summerhouse is fake. A friend of Doris Frรถse confirms that the man whom Doris Frรถse was visiting in Denmark was Manfred Schlosser. In the mean time, Pernille, the wife of Manfred Schlosser, finds knives and photoalbums of many murdered women in the attic. Manfred finds out and drowns her in their bathtub. Manfred is taken into custody, but denies everything.
