Brain Drain

A dim-wittedd man discovers a cursed trefinator in a museum warehouse: a guillotine-like device that transfers spinal fluid from one individual to another. The cursed item actually transfers intelligence as well, and the man uses it to make himself intelligent by preying upon doctors at the museum. Jack and the others become involved when Jack's old girlfriend and fiancee goes to work at the museum, and is the next target for the trefinator.
