Class Reunion

June 1972. Bob Spinnaker, and his entire class, pull a prank on their classmate, Walter Baylor, sending him to a mental institution. Ten long years later, the class of Lizzie Borden High--including Gary Nash, Hubert Downs, and Meredith Modess--is going through the motions at their class reunion, where Chuck Berry is performing, unbeknownst to them that deranged Walter has escaped from the mental hospital, bent on crashing the party. Now, as unsuspecting guests start disappearing, the boys and girls of Lizzie Borden High must spring into action, and expose the madman. But, can they do it in time, and save the class reunion?
