Zane Wolf is a radio disk jockey for a small radio station whose marriage is on the rocks and is also having an affair with another woman who ignores him. But there's a serial killer loose whom kills women every full moon in their houses with a surgical laser. Cynical veteran police detective Musso is paired with naive rookie Barbara Fleck to find the killer before he strikes again. The detectives paths with Zane cross when a creepy young man, named Andy, phones the radio station after every killing to confess and taunt Zane about the killings. Musso and Fleck decide to set a trap for Andy, while Zane has other plans of his own for the mysterious masked killer.
