Juice (1973)

Collette is a passionate French girl who is looking for sex in all the wrong places. She goes to a shrink, Guy Thomas to talk about her obsession but he is no help as he is too preoccupied with his own head nurse. Then she seeks the help of a cult priest but realizes he has no answers, either. She tries a threesome with her oversexed girlfriend but ultimately it is the unexpected entrance of a mysterious man in a cape and top hat that finally helps Collette realize her sexual ambition.
