Dead of Summer (1970)

Joyce is the bored wife of an Italian architect; they live in a luxurious apartment in Morocco, but today she's all alone in it since he's away on business. A heatwave causes her to sweat profusely, so she decides to take a bath and play with an ice cube naked. She notices men peeping at her through the window, which disturbs her. While looking through her husband's things, she finds a blow-up doll and curiously toys with her. Later she's visited by a maid and they get the place ready for a party. A sandstorm outside calms a bit, so Joyce decides to take a ride to the beach and take a walk there. Her car get stuck in the sand and a local and his camel help her out. Back home, she listens to tapes her husband has made and watches TV. She sees her neighbors having sex through her window, which turns her on, so she tries to seduce a local boy outside of the building, but he runs away in terror, frustrating her. Her doctor visits her and takes her to see his clinic. She seems to be slowly unraveling psychologically.
