The Night of the Following Day
R, 1968
An attractive teenage girl (Pamela Franklin) of a wealthy father (Hugues Wanner) is kidnapped on her way out of the airport by a man pretending to be a chauffeur, Bud, (Marlon Brando) and a guy who jumps into the car credited as Leer (Richard Boone). It turns out the blonde stewardess Vi (Rita Moreno) from the flight the girl was on is in on the job, as well as her brother, Wally (Jess Hahn).
A simple kidnapping for ransom rapidly escalates when Bud the chauffeur realizes that Leer is a sick, twisted S.O.B. with a taste for teenage girls. The stewardess, Vi, also Bud's girlfriend and Wally's sister, has a serious drug problem on top of Leer's fetish, and Bud wants out, and not just out, but to stop the whole thing and give the girl back. But this isn't the kind of story where everything goes the way you want it. At all.
