La orca (1976)

The kidnappers in this movie though are pretty low-rent types, barely connected to the Mafia. Their victim is a very spoiled, but perhaps not especially rich, teenage girl (Rena Neihaus) whose parents seem unable–or perhaps unwilling–to get her back In this movie the youngest, most handsome kidnapper (Michele Placido) falls for the girl in kind of a reverse Stockholm syndrome, with tragic results for at least one of them. The end of movie, strangely enough, is kind of reminiscent of "Last Tango in Paris". This movie is very class-conscious in the way it has this poor Sicilian boy falling for a rich, northern girl (the Italian title "La Orca" comes from the designer outfit she's wearing).
