In 1943, a small commando team is sent to destroy huge German guns on the Greek Island of Navarone in order to rescue Allied troops trapped on Kheros. Led by British Major Franklin (Anthony Quayle), the team includes American Mallory (Gregory Peck), Greek resistance fighter Stavros (Anthony Quinn) and reluctant explosives expert Miller. Facing impossible odds, the men battle stormy seas and daunting cliffs. When Franklin is injured, Mallory takes command, and personal enmities spill over.
