There was a movie I would categorize as suspense/thriller in the early eighties I could have SWORN Victoria Tennant starred in it but I guess I was wrong because Ive looked everywhere including IMDB. Several people check into a clinic of sorts where they hope to quit smoking, lose weight etc. The only thing is the tactics used at the clinic are humiliating and down right torturous...and once the "clients" are checked) in there's no checking out (no means of escape) unless or until they're "cured".
