The remnants of an American infantry platoon (led by Robert Ryan), cut off and behind enemy lines, must somehow make it past North Korean snipers, artillery barrages and infiltrators to complete a long march to the last known location of their division's HQ. En route, they encounter a firebrand sergeant (Aldo Ray) and his shell-shocked commanding officer (Robert Keith). Will the chance encounter help,or hinder the platoon's desperate march to safety? Co-starring Vic Morrow, L.Q. Jones, and Nehemiah Persoff.
