In 2003, thirty years after they served together in the Vietnam War, former Navy Corps medic Richard "Doc" Shepherd (Steve Carell) reunites with ex-Marines Sal (Bryan Cranston) and Mueller (Laurence Fishburne) on a different type of mission: to bury Doc's son, a young Marine killed in the Iraq War.

Doc decides to forgo burial at Arlington Cemetery and, with the help of his old buddies, takes the casket on a bittersweet trip up the East Coast to his home in suburban New Hampshire.

Along the way, Doc, Sal and Mueller reminisce and come to terms with shared experiences of the war that continue to shape their lives.
