A special request from my sister with whom I can quote half of the movie from memory. Serial killers! The Cannes Film Festival! Glamour! Murder! Communism! Giant mouse traps! If you loved Airplane then this is your kind of humour.
A second-class horror movie has to be shown at Cannes Film Festival, but, before each screening, the projectionist is killed by a mysterious fellow, with hammer and sickle, just as it happens in the film to be shown.
