In Tandem

The Evil of the Depths (2x5)

Air date: Jun 05, 2018

While visiting some caves highly appreciated by speleologists, a group of tourists discover a woman lying in a cavity where descents are usually made. When they get out of the caves to the surface to ask for help and the police manage to reach the place, the body has disappeared. Apparently the woman is Lina Bernard, a professional speleologist and it seems unlikely that she has had an accident.
