A former secret agent is sent to retrieve a priceless collection of stolen jewels from a Lisbon nightclub owner who worked both sides during World War II.

American soldiers, captured by North Korean's, are periodically brainwashed into giving up their capitalist ways to join the communist movement.

A Soviet nurse helps a U.S. pilot, his buddies and a scientist escape from North Korea. American International Pictures originally distributed this film as a double feature with "Suicide Battalion".

Yul Brynner plays political leader Sharif who is sprung from a police van on his way to a firing squad by young loyalists led by Sal Mineo. Yul and the other prisoners kidnap an ambulance and head into the Arabian desert with the police in hot pursuit. All the performances are magnificent: Sal Mineo showing his acting talents, Jack Warden in a wiseguy performance as an employee of Zahrain oil who was involved in embezzlement, Anthony Caruso as a slimy psychotic and the underrated Madlyn Rhue as a nurse who becomes emotionally involved in the proceedings.
