Unit One is called to Aabenrå when parts of a woman body is found in Knapsø. 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 Fröse. 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 Fröse, but the name of the man who borrowed the summerhouse is fake. A friend of Doris Fröse confirms that the man whom Doris Fröse 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.
