Smoker (1983)

Overview  

Sharon Mitchell is a leftist revolutionary whose sex boutique serves as very effective cover. But now she's blown it big time. One of the vibrators in her shop contained a super-sophisticated bomb. But Sharon lost track of it and sold it to Troye Layn who intends to give it to her girlfriend Diana Sloan. When she gets the gift home and her girl unwraps it, they try it out together. Little do they know that their kinky landlord Davis Christopher is watching through a two-way mirror. When the girls go out for a bite to eat, David steals into their apartment, puts on some of their clothes and makes off with the vibrator. But Sharon is right after him, on the trail of the vibrator, and she's willing to do anything to get it back.
