Blow Job (1980)

Stefano Vicinelli and his girlfriend Diana fall two weeks behind on their hotel rent and face having their luggage and car impounded until they can pay the bill. Conveniently for them, a distraught woman in the room right above theirs leaps to her death from the window. Using that as a distraction, the lovebirds sneak out and take off. Running low on money, they pool what little cash they do have and go to the racetrack. Stefano encounters a crazed woman wearing sunglasses who demands he give her a key so she can unlock a door. After she calms down, she proposes a deal with him: She'll help him win money in the horse race if he'll help her "get past the gate." Having no clue what she's even talking about, Stefano reluctantly agrees and bets on her suggestion. After the horse wins and he collects, he feels obliged to accompany the strange woman - who introduces herself as Countess Angela - back to her home.
