Kolchak: The Night Stalker - Season 1 - Episode 15

The strange disappearance of an antique motorcycle is the first indication of trouble. What follows are a rash of murders where each victim is decapitated with superhuman force by what witnesses report is a headless motorcyclist. As Kolchak investigates, he discovers that the victims were all members of a cycle gang back in the 50's. A prank they played on a rival gang member, Harold "Swordsman" Baker, resulted in his unintentional decapitation. Baker's ghost killed several of their gang back in the 50's until his head was reunited with the rest of his corpse. However, the cemetary where Baker was interred was dug up and his head and body separated once more. Now, Kolchak must reunite the head and body once more before the headless cyclist finishes off the gang.
