The film opens with a news report of a revolution that has overthrown the Iranian government. This coincides with the disappearance of an American UN chemical weapons inspector, Dr. John Van Tasset (Barry Livingston), in Iraq. The US is determined to stage a rescue in the fear that he will be used to develop weapons for the new Iranian government. A Navy SEALs team is recruited for the mission, but is down a member due to illness. Enter Bob Rodgers (Billy Warlock), a young SEAL fresh out of school. The SEAL team is flown out to an aircraft carrier in the Persian Gulf where we meet Adm. Jim Perry (Billy Dee Williams) who commands the fleet and the rescue mission. The SEAL team will be dispatched from a submarine to rescue the scientist from where he is being held in Iran.
