Amsterdamned is a 1988 Dutch crime thriller with slasher film elements directed and written by Dick Maas, and stars Huub Stapel, Monique van de Ven, and Serge-Henri Valcke.

A bag lady watches from a distance as the killer plunges the knife into the hooker and drags her back into the water.

The next morning, a tour boat on the canal collides with the body of the prostitute, who has been hung on one of the small bridges.

That night, two environmentalists are taking water samples in an ongoing investigation against a nearby chemical plant.

Scared, the surviving environmentalist swims to the nearby shore and calls for help when he sees a truck pass by.

As Eric begins to get frustrated with nothing turning up, he and John eventually think they find a suspect in a former chemical plant employee known for his violent outbursts.

Eric eventually tracks the killer to a local sewer only to be shot at close range in the shoulder with a harpoon gun.

Martin finally confesses that the killer is a childhood friend of his and fellow diver who was shunned by society after a commercial diving job caused him to be disfigured by uranium hexafluoride poisoning.

The film was given a limited release, grossing $14,819 on five screens in its opening weekend in North America, and a total of $98,003 over its entire run.

The speedboat chase scene left Huub Stapel out of production for three weeks when the boat he rode in crashed on the set of the film.

A scene in which the killer drives his speedboat off a ramp from one side of a bridge to another had been seen in a few cinema programs on U.S.-based station TLC.
