Party Line

In this 80's slasher, a deranged pair of siblings prey on married men looking for a little action on the side using a local party line. After Lt. Dan Bridges comes across the aftermath of their most recent murder while pursuing a drug dealer at a nightclub, he teams up with the new Assistant DA, Stacy Sloane, to track them down. As Lt. Bridges wears out the patience of his Captain, played by Richard Roundtree, and the body count rises, the duo must find a way to lure the murderous brother and sister into a trap of their own.
