Back From Eternity

On a plane bound for South America, the son of a mobster travels under the protection of henchmen who learn in-flight that their boss is dead. Also on the flight are weary war pilot Bill Lonagan (Robert Ryan), prostitute Rena (Anita Ekberg), Jud Ellis (Gene Barry) and his fiancée, Louise (Phyllis Kirk), and a convicted murderer (Rod Steiger) who's bound for his execution. After a storm forces the plane down in a jungle, the passengers turn against one another in their struggle to survive.
