Easy Company is introduced to Captain Sobel, who has the group undergo hard and unfair training. As a result, Sobel comes into conflict with his men, including Richard Winters, his executive officer. The company is shipped to England to prepare for D-Day.

With the addition of many new men, Easy Company heads to Holland to participate in Operation Market Garden and prepare an Allied route into Germany, but they meet stiff German resistance.

Winters writes a report on the challenge of an unexpected resistance to a German attack, and is haunted by his conscience after shooting a teenage German soldier. Operation Pegasus is depicted. Easy Company is called to Bastogne to repel the sudden German counterattack.

Easy Company is in Hagenau in Feburary, 1945, where they prepare for a night patrol mission to capture German prisoners. The patrol includes one veteran who is despised for missing Bastogne and a new lieutenant fresh out of West Point.

As the Allies move into Germany and the war comes closer to an end, disillusionment and anger set in for Easy Company--until they stumble onto a concentration camp abandoned by the German military.

As the Germans surrender, it appears that that the hard days for Easy Company are over as they are stationed in Austria. But they soon learn that those solders without enough service points will be sent to fight in Japan.
