Lt. Daniel Kaffee (Tom Cruise) is a military lawyer defending two U.S. Marines charged with killing a fellow Marine at the Guantanamo Bay Naval Base in Cuba. Although Kaffee is known for seeking plea bargains, a fellow lawyer, Lt. Cdr. JoAnne Galloway (Demi Moore), convinces him that the accused marines were most likely carrying out an order from a commanding officer. Kaffee takes a risk by calling Col. Nathan R. Jessep (Jack Nicholson) to the stand in an effort to uncover the conspiracy.
After the Cold War, a breakaway Russian republic with nuclear warheads becomes a possible worldwide threat. U.S. submarine Capt. Frank Ramsey (Gene Hackman) signs on a relatively green but highly recommended Lt. Cmdr. Ron Hunter (Denzel Washington) to the USS Alabama, which may be the only ship able to stop a possible Armageddon. When Ramsay insists that the Alabama must act aggressively, Hunter, fearing they will start rather than stop a disaster, leads a potential mutiny to stop him.
