In 1991, a crisis built on political maneuvering and fear spirals into a near-morphic slice of history where a single act could ignite a full-scale nuclear war. A missile is launched from a NATO-friendly site in Turkey toward Donetsk, and Soviet automated defenses interpret it as a NATO strike, responding with a measured volley of intercontinental missiles aimed at the United States. SAC Commander General Renning pushes hard for a broad counterstrike, and the President, [Martin Landau], faces a harrowing choice as the stakes climb higher and higher. The Soviet leader explains the dissidents’ actions and offers a chance to stand down, but warns that a direct, all-out exchange would cost millions and could unravel both nations.
As a second, even more devastating blow seems imminent, the President reluctantly authorizes a multi-part assault: first the ICBMs, then submarine-launched missiles, timed with bomber advances over the Soviet Union. The burden of control shifts to the Air Force’s flying command post, the Look-Back-in-the-Sky plane known as Looking Glass, steered by the pilot codenamed Alice, [James Earl Jones]. The plan unfolds against the threat of escalation, and a B-52—call sign Polar Bear 1—takes off from Fairchild Air Force Base under Major Cassidy, [Powers Boothe], and Captain Moreau, [Rebecca De Mornay], as the crew fights to keep their nerve when the lights flash and the world tilts toward catastrophe. Moreau, partially blinded by the blast, struggles to keep the bomber on course while a crewman is killed in the brutal wake of the first strike. The mission presses forward through hostile skies as Soviet interceptors close in.
On the political-and-command side, the Nightwatch team fights to hold together a fractured chain of command. Admiral Harpoon, [Jeffrey DeMunn], briefs Condor about the grim math and the fragile balance of power, while Colonel Fargo, [Rip Torn], lobbies for a relentless, hawkish approach that could push the world over the edge. The President is found gravely injured after Marine One is forced down and is evacuated to a FEMA shelter where the crisis continues to unfold. The tension at the shelter is palpable as the civilian leadership grapples with the consequences of every order sent from the war room, and Harpoon conveys the fear that the retaliation could spiral beyond control.
Tragedy slices through the ranks as Tyler, [Glenn Withrow], a crew member haunted by personal loss, takes his own life by ejecting without a parachute, leaving the rest of the crew to confront the consequences as their mission unravels. The intelligence comes back with a startling turn: Looking Glass detects that Polar Bear 1 appears to retreat, and a Soviet squadron seems to pull back as well, suggesting a potential de-escalation—but Condor overrules any pause, insisting on continuing the attack and ordering Nightwatch to push forward with the submarine strike.
The President eventually reaches out to Alice and attempts to recall the remaining bombers, but Condor remains in command and orders the Nightwatch to transmit launch orders to the submarines. The Looking Glass crew must act decisively, and in a final act of defiance they choose to ram their aircraft into Nightwatch to halt the escalation before Condor’s orders can be fully broadcast. The President succeeds in issuing a stand-down, and Cassidy and Moreau, realizing their fuel will not last, glide toward the horizon with dawn breaking on a fragile future. In those last, quiet moments, the world is spared from a total catastrophe, and the hope for a safer tomorrow feels earned—even as the costs and losses of the day linger.
