Looking for the original title of a US movie, shot on film, likely in the early 80s (german title: Love Machine), starring Jessie St. james and John Leslie.
He's a member of the criminal underworld, meet with her in a bar, and fell in love at first glance... but in the end she'll abandon him, no sooner than she have taken away all his own money.
Also Mai Lin plays, as holder of a brothel where John goes with a red-haired woman, before meeting with Jessie.
