Ken Wahl (The Soldier), Lesley Ann Warren (Cop), Donald Pleasence (The Black Windmill), George Peppard (Cannon for Cordoba) and Bruno Lawrence (The Quiet Earth) co-star in this action-adventure yarn about a group of people in search of a missing plane with a cargo of $50,000,000. Barney (Wahl) and Gilbert (Pleasence) are local hunters with an ancient helicopter who first find the submerged wreck of The Yankee Zephyr. Sally (Warren), who runs a local mission, is persuaded to invest in their search?on the condition that she can tag along. Unbeknownst to them all, Theo Brown (Peppard) and his gang of mercenaries are watching and waiting for their chance to move in on the treasure. Treachery and hilarity go hand in hand as these unlikely soldiers of fortune vie for the vast wealth of The Yankee Zephyr?in this most entertaining and exciting adventure directed by David Hemmings (The Key to Rebecca) with a rousing and memorable score by Brian May (The Road Warrior).
