Based on a true story, it tells the heroic experience of Don Smith of the 94th Infantry Regiment in the Battle of the Bulge. In December 1944, when the German elite infantry and the skeleton armored division quietly entered the snow-covered mountain forest position at the border between Germany and Belgium, an alert American soldier and his squad colleagues were ready to defend. Their position was located at the forefront of a small town, which was the forward position of the US military's advance into Germany. The position was very critical. In this famous Battle of the Bulge (Battle of the Ardennes) in World War II, although the weapons and personnel were far inferior to the enemy, Sergeant Don Smith fought many insurmountable difficulties for hope and courage at this decisive moment. Their squad of the 94th Infantry Division dug a ridge outside the town, but no senior US military commander believed that the Germans would attack in a blizzard with sub-zero temperatures. The Germans launched an attack before dawn, and communications were interrupted. Don Smith had no choice but to rush into the town without weapons and wounded in the hail of bullets to report the German attack to his superiors. Based on a true story, the film shows Don Smith's heroic deeds and his struggle between desire and duty. The cruel reality of war made him realize that losing hope is worse than losing life. One man's courage, one man's hope, everyone's war.
