Sam must protect an old girlfriend (Chris Butler, played by Susan Anspach) - who married a rich gangster - from other gangsters, flying her from USA to Mexico City. The great thing about this movie is the helicopter scenes; with amazing maneuvers and a lot of dogfighting. The movie gets to it's climax when Sam and Chris find themselves trapped by the gangsters and call Sam's old army buddies for help. This movie is worth watching because of the helicopters and planes. A real good classic.
