That night, two environmentalists are taking water samples in an ongoing investigation against a nearby chemical plant. However, when the killer emerges, one of the men is taken underwater and when his partner attempts to grab the anchor, he is horrified to find the man's head on the anchor. Scared, the surviving environmentalist swims to the nearby shore and calls for help when he sees a truck pass by. As the truck driver comes out from a distance, the killer grabs the environmentalist and drags him back into the water.
