Creep

"Murder runs in the family bloodline, and the only hope to stop a brother and sister who share an insatiable appetite for killing lies in a father-and-daughter police team in this blood-spattered effort from low-budget horror legend Tim Ritter. As the bodies pile up and the blood flows in rivers, every taboo is transcended. When a startling connection between the killers and the duo who longs to put an end to their murderous rampage raises the stakes of their deadly cat-and-mouse game, the stage is set for an explosive finale that is bound to blow the mind of even the most jaded gore-hound."
