This war movie is set on the high-seas during WWI. It chronicles the exploits of a brave English sailor who is captured by a German cruiser. The courageous sailor, the bastard of a RN officer, soon escapes from the German ship. He also steals a rifle. He hides on the shore and begins taking pot-shots at the Germans. Due to his marksmanship, the ship's journey is delayed. While the Germans are hunting for him, the British ships sneak up and sink the enemy boat. Unfortunately the brave sailor is killed. He becomes a hero and the British erect a cross on the highest point on the island to commemorate the young hero. The commander of the British ship is disturbed to discover that the dead hero was the son he denied having. This drama is considered to be a landmark British film; it is the first to utilize the actual Royal Navy and it's ships.
