A developer moves a cemetery as he prepares to build. But carelessness allows an old evil, once laid to rest, to return again: a motorcyclist with no head, resuming an old agenda of revenge for a prank gone horribly wrong. As usual, Kolchak finds himself in the middle of it, and if he's not careful he may lose his own head.

An Aztec ritual spells doom for physically fit victims in Chicago... and Kolchak must stop the last sacrifice before an ancient god is resurrected.
