This drive-in B-movie classic has dysfunctional college boy Tony (a young Michael Landon) attending hypnotherapy sessions to cure him of his antisocial tendencies.
Unfortunately, he ends up with an unscrupulous therapist who uses regression therapy to send him on a lycanthropic rampage.
He kills a friend in the woods, a girl in a gymnasium and finally his doctor before being rounded up and shot.
