A mysterious diver hiding in Amsterdam's canal system embarks on a rampage of gruesome murders, terrifying city officials and leaving few clues for the city's best detective, who doesn't suspect that both his new girlfriend and twelve-year-old daughter may be closer than he is to finding the killer.
Practical Effects
Scuba-slasher costume is gloriously ridiculous practical effects.
Direction
Dick Maas somehow makes canals visually interesting. Respect.

That speedboat chase through Amsterdam is legitimately bonkers.

Dick Maas
Trivia, insights & behind the scenes
Director Dick Maas later remade this as 'Down' in 2001, set in a New York elevator, proving he has a thing for confined spaces with murder potential.
This was the most expensive Dutch film ever made at the time, and Amsterdam's tourism board reportedly had mixed feelings about their canals becoming a horror setting.
