An oil company enlists four destitute drifters -- Mario (Yves Montand), Luigi (Folco Lulli), Bimba (Peter Van Eyck) and Jo (Charles Vanel) -- for a dangerous mission transporting volatile explosives across Central America's treacherous terrain. Packed with nerve-racking tension that never lets up, director Henri-Georges Clouzot's gritty masterpiece took home the Grand Prize at the 1953 Cannes Film Festival.
