Why Girls Walk Home (1929)

Four young women change a flat tire and, feeling hot and bothered, leave their car to go take a swim in the ocean..... and their underwear is less revealing than one-piece bathing suits. While they are frolicking in the surf, a young Black girl comes by and steals their pretty clothes.... and their car has mysteriously vanished, leaving them the grim prospect of having to walk home.... although somehow I imagine some kind man would be happy to pick them up.
