About Could This Be Love (1973)
Jacky is a young woman living in Greenwich Village who is an artist and hangs out with her best friend Renee. After finishing her latest drawing for the day, Jacky and Renee travel to a low-rent bar and pick up a prostitute, named Cathy. After having a lesbian threesome with her, they invite Cathy to a dinner party being given in honor of Mr. Gatto, a department story purchaser interested in a range of shoes made by Jacky's husband, Michael. Also at the party is Renee's husband Stephen, and Stephen's pianist friend Dennis. Renee introduces Cathy as her cousin to Mr. Gatto and everyone else.
As the evening progress, Mr. Gatto strikes up a friendship to Cathy, while Jacky and Renee secretly express their contempt for her. Mr. Gatto explains his business dealings with Dennis and about his ability to make profit from his sales purchases. Dennis and Cathy are intrigued, but everyone else is just bored. Cathy has a little too munch to drink, and retires to a bedroom. Mr. Gatto follows her there, where he talks more with her about his admiration of her beauty and ability to influence people. But instead of taking advantage of her, Mr. Gatto says his goodnight, and leaves.
As Jacky and Renee clean up after every one, they talk with Stephen about how stupid and snobbish Mr. Gatto was, and about how Cathy is such a prude. Cathy, overhears them from the bedroom and looks on in the dark, empty bedroom with unmistakable depression.
