The fire ignites during initial testing of the building's electrical systems when a short-circuit occurs on the 81st floor. Roberts later discovers that Roger Simmons had compromised the wiring, which allowed the fire to spread rapidly throughout the skyscraper.

Doug Roberts invents a gravity brake mechanism for the scenic elevator that allows a group of 12 people, including his fiancée Susan Franklin, Lisolette, and the children, to make a perilous descent to safety. The elevator becomes unstable after an explosion on the 110th floor sends Lisolette to her death.

Chief O'Hallorhan and Doug Roberts detonate the water tanks atop the tower as a desperate measure to save the remaining guests trapped in the Promenade Room. The explosion unleashes a massive torrent of water that cascades through the building, successfully extinguishing the flames and allowing many more people to survive.

The survivors escape through multiple rescue efforts. A Navy rescue squad attaches a breeches buoy between the Promenade Room and the roof of the adjacent Peerless Building, allowing some guests to escape. Those remaining are saved when O'Hallorhan and Roberts detonate the water tanks to douse the flames.

Foreshadowing: Earlier, Roberts had to find an alternate route through a ventilation shaft because the Promenade Room entrance was blocked by solidified cement.

The express elevators fail when the fire engulfs them, trapping and killing several people whose elevator stops on the burning floor. Later, when firefighters work to control the blaze on the 65th floor, the electrical system fails completely, causing the passenger elevators to shut down and forcing O'Hallorhan to rappel down the elevator shaft for safety.

As the fire rages through the building, a gas line explosion devastates the stairwell, making escape impossible for many trapped occupants. This explosion also demolishes the stairwell, isolating Roberts and others from further escape routes and forcing them to find alternative ways to reach the trapped guests.

The helicopter rescue attempt fails when two women recklessly rush the aircraft on the roof, causing it to crash and ignite flames. This disaster forces the Navy rescue squad to step in with an alternative method using the breeches buoy to evacuate guests to the adjacent Peerless Building.
