The man claims he is Olaf Witte, who disappeared without a trace from the village 25 years ago. If it is him, what does he know about Alice Drost, a teenage girl who disappeared at the same time as Olaf?

After her boat is found floating on the lake, an extensive search gets underway for Maud van Keulen. Is there a connection between her disappearance and the possible return of Olaf Witte? The Criminal Investigation Department is called in to help. Then something is found on the water.
