Deep below the jungles of Vietnam inside a maddening maze of tunnels, a squad of U.S. soldiers led by Sgt. Vic Hollowborn (Michael Paré) faces death and inhumanity on a suicide mission to unearth the Viet Cong enemy. Groping through the dark, cramped underground labyrinth, the men search for what they cannot see -- and can only hope to find a way out alive. Uwe Boll directs this unflinching look at a rarely depicted piece of Vietnam War history.
