A hotel is set on fire in Nyborg, killing 32 people. A local pyromaniac, Henning Jørgensen, is taken into questioning, but fails to answer where the fire started. In a side story, a little boy witnesses how a bespectacled man places the corpse of a young woman on a bench in a parking lot. In a picture from the local newspaper, a face is very faintly viewed in the background, and the police trace the person in the picture to be Otto Lykke Larsen, a mentally retarded man. Larsen is taken into questioning. In the videos found in Larsen's apartment, fires are videotaped and Unit One suspects that Larsen was the pyromaniac responsible. In other videos, Larsen has sexual intercourse with a woman, Britt Hjort Jespersen. In questioning, Larsen admits that he was the one who set fire on the hotel, along with all the other fires recorded in his videotapes. In the mean time, the corpse of the young woman is identified as Jespersen. Larsen admits he killed Jespersen. (thetvdb.com)
