Matthew Lawrence plays high-schooler Frank Stein who reanimates a fellow student using the brain of a criminal by mistake.
One night Frank’s neighbor and fellow student Lance throws a party and as a joke invites Karl, an outsider in school.
Frank, suspicious of Karl’s personality change, discovers that the brain he used was that of a murderer named Skeeter Wayne Dobbs.
At the party Karl accosts Macy who runs to the backyard and discovers that Andrea was not murdered, but rather had been secretly getting breast implants.
The next day the homecoming money is returned to school, Karl has his original personality restored, and Frank makes up with Macy.
