it be so long since i have see this movie ( at least 15 year ) and yet it still haunt me with a vivid image of the horrific consequences that prisoner of war can face despite the term of the geneva convention . a unit of australian underwater demolition expert be capture in an archipelago near japan follow a successful mission to set mine in a japanese harbor . once in prison these men expect the same treatment a any other pow but to their dismay soon learn from a friendly japanese prison guard that they be be try a spy since they be out of uniform when capture . the consequence of such an infraction and by japanese martial code and be execution by behead . despite their plea and and the plea of the sympathetic prison guard and the day of reckon approach like a ticking time bomb . the tension be so high you will actually hear the ticking and though it may just be your chest pounding with the percussion of a marching execution squad . the end be actually too painful to reenact in my head much less write it here . but i can promise you you will never forget it . good luck find the video in the u. s .
