Humanoids from the Deep (1980), also known as Monster, is a cult-classic sci-fi horror film directed by Barbara Peeters. It blends elements of creature horror and exploitation cinema, delivering a mix of thrills, gore, and shock.The story is set in the small coastal fishing town of Noyo, California. The town’s economy relies heavily on fishing, but local fishermen face a declining salmon population. To solve this, a company called Canco introduces genetically engineered salmon to boost their numbers. However, these experiments inadvertently result in horrifying consequences.

The genetically altered salmon escape into the ocean, triggering an evolutionary mutation in the local fish population. This leads to the creation of humanoid sea creatures—large, amphibious monsters with grotesque features, sharp claws, and a primal drive to reproduce with human women in order to further their species.
As the creatures begin to emerge, they wreak havoc on the town. They attack fishermen, destroy property, and abduct women. The situation escalates as a local carnival becomes the site of a full-blown massacre by the humanoids. Amid the chaos, townspeople must confront both the terrifying creatures and the ethical ramifications of the genetic experiments that led to the disaster.
