Chris Collins is a teen whom resides in a state of irreversible sexual stimulation. He seems to exist rich and varied sex lifetime involving simply about every woman he fulfills but, unfortunately for Chris, these experiences exist just in his too hot mind. At school Chris is smitten by a new girl on campus, the beautiful blonde, Beth Lowell. His obsession with Beth does not go un-noticed by the school bully Norman, who manoeuvres him into betting his car that he cant get into bed with Beth in one week. Chris is desperate and appeals to a newly-arrived neighbour, the worldly sophisticated Michelle for advice and gets more than he ever hoped for. Sylvia (Emanuel) Kristel plays Michelle. The Big Bet was directed by 50"s scifi/horror maestro Bert I. Gordon.
