Pardon My Nightshirt (1956)

A seductive alien prowls the streets of Glasgow in search of prey: unsuspecting men who fall under her spell.

Frank Ripploh is a bit of a rascal: he's a bearded and shaggy-haired teacher, and he's gay with a very active sex life and an interest in making films. He keeps his personal life and teaching separate, but he sometimes corrects student papers in public toilets as he waits to score. He cruises constantly, and one evening, he meets Bernd. They become lovers. While Bernd is attentive and caring, Frank gets bored and continues his polymorphously perverse ways. For how long will Bernd and Frank tolerate each other's habits, and for how long can Frank keep his sexual orientation out of the classroom? Things come to a head during Berlin's annual Queen's Ball and the morning after.

An isolated house is too remote for a lone servant, who leaves a note, quietly exits the back door, and puts the key under the mat. Left alone in the house is a mother and her infant. A tramp has watched the servant leave and begins to skulk. When the lady of the house sees him outside as he discovers the key, she's terrified and desperately phones her husband, who's at work in town. He jumps into a car that's idling in front of his office and races toward home, the car's owner, and police, in hot pursuit.
