The vampire is chased by cops and authorities throughout the film. He throws a person out of the window to his death in the street below. There are some hand-to-hand combat and a scene in which the vampire beats a woman unconscious before drinking her blood offscreen.
The vampire ties a woman down and keeps her captive, draining blood from her arm via a tube, using her as a private "blood bank."
Kolchak pounds a wooden stake through the vampire's heart at the end. There is little to no blood, but the scene is very intense.
