Brian Renney, storied Captain of the Vietnam War, is losing his battle against scars of body and mind. His son, Jason, is torn between the woman he loves, and the demands of an embittered father. But war is coming. Someone from Brian's past has built an army in secret beneath Antarctica, seeking vengeance against the Renneys for reasons unknown. With their family under attack, father and son must face a threat that plagues them from cold shadows - and gain an ally who, once meant for evil, will make legends of them all.
