 In 1987 the chief led his first case as head inspector, searching for a missing young woman. However, she was never found. Two months before the case is exactly 20 years ago, which would make it too old to lead to a conviction if the murderer were found, the chief asks Grijpstra and De Gier to re-investigate. He also calls in a psychic who successfully locates the body. DNA traces of the murderer are found, and the chief is eager to acquire a DNA sample from Jack Ebbits, who was the prime suspects at the time. Ebbits is not very eager to participate, however. Grijpstra recognizes another suspect as a member of a mob who beat him up during the crowning of Queen Beatrix on April 30, 1980, when he was just a rookie.
