Room 69 (1975)

Blessed, or cursed, with the gift of beauty, a statuesque flight attendant and single mother-of-one finds herself with her back to the wall after a fateful encounter with a charming but duplicitous member of a vicious drug-smuggling ring. Now, there is no turning back, and as the helpless woman succumbs to blackmail, she must summon up every last ounce of courage to play along and do their bidding to reunite with her kidnapped child, enduring humiliation and sexual abuse. But what secrets lie hidden behind the door of Room 69?
