Force Majeure (Uncontrollable Circumstances) begins with a drug deal involving tourists Phillipe (Patrick Bruel) and Daniel (Francois Cluzet), and a Dutch stranger. Two years pass: the Dutchman has been arrested in an unspecified Asian country, where the penalty for drug trafficking is death. Phillipe and Daniel agree to admit that the hashish partly belongs to them, which will reduce the Dutchman's sentence, but also subject the twosome to a prison sentence themselves. Malcolm Forrest (Alan Bates), a representative of Amnesty International, does what he can to aid all three of the unfortunate young men. Force Majeure was co-written by Michele De Broca, wife of director Philippe De Broca.
