It's night on a Paris bridge. A girl leans over Seine River with tears in her eyes and a violent yearning to drown her sorrows. Out of nowhere someone takes an interest in her. He is Gabor, a knife thrower who needs a human target for his show. The girl, Adele, has never been lucky and nowhere else to go. So she follows him. They travel along the northern bank of the Mediterranean to perform.

Eric and Ramzy are working as window washers at the Montparnasse skyscraper in Paris. Thinking that he has a date set up with beautiful executive Marie-Joelle (who in reality hates his guts), Ramzy stays at work late while Eric hangs around with him. As a result, the pair witness a gang of terrorists seize the tower and take its late-night occupants (including Marie- Joelle) hostage. Knowing that only they can save the day, Eric and Ramzy swing into action.
