The Cannon of Navarone

The Nazi army installed two super-powerful cannons on a Greek island in the Aegean Sea, which threatened the safety of the British troops on neighboring islands. So six Allied and Greek soldiers were ordered by the British to sneak into the island under the leadership of the officer Major Franklin. After meeting with the guerrillas on the island, they carried out the task of destroying the cannons. But when Major Franklin is injured in the mission, Colonel Casey's inexperience spoils the situation. Soon after, they discovered a traitor in the team, which led to a rift between Colonel Casey, demolition expert Corporal Miller and the Greek guerrilla Andrea. Can these six strong men complete this arduous task?
