Girls with dirty hands (Koritsia me vromika heria) - Трилъри, 1977

The laconic synopsis says "An erotic adventure of two young people against the American underworld."
In fact the movie mainly follows the story of a young girl called Aliki (Alice) through her various misfortunes and misadventures, half of the time told in flashbacks and with the staple Greek voice narration. There isn't much of an 'American Underworld' to be found though, except maybe for 3 tough guys speaking Greek.
She moves in with a backstabbing couple only to get involved into a murder plot, then falls into the hands of a backstabbing gang, then escapes with a stoner hippy and on and on, until she meets the good guy. Generally she gets dragged around a lot and she gets violated a couple of times. The female antagonist (which i suppose is "Miss America" also gets laid a lot, and on her own free will. Meanwhile the Police tries to solve the puzzle.
As with most Greek tragedies, this one also ends by the beach.
