Summer 1863. The Confederacy pushes north into Pennsylvania. Union divisions converge to face them. Two great armies will clash at Gettysburg, site of a theology school. For three days, through such legendary actions as Little Round Top and Pickett's Charge, the fate of "one nation, indivisible" hangs in the balance. Tom Berenger, Jeff Daniels, Martin Sheen, Richard Jordan and more play key roles in this magnificent epic based on Michael Shaara's Pulitzer Prize-winning The Killer Angels, filmed at actual battle locations and rigorously authenticated down to the boots.
