The Towering Inferno

Plot

Architect Doug Roberts returns to San Francisco for the dedication of the Glass Tower, a mixed-use skyscraper which he designed for developer James Duncan. The tower, tall and 138 stories, is the world's tallest building. During testing, an electrical short-circuit starts a fire on the 81st floor just after another short occurs in the main utility room. While examining the latter short, Roberts sees the wiring is inadequate and suspects that Roger Simmons, the electrical subcontractor and Duncan's son-in-law, cut corners. Simmons, however, feigns innocence.

During the dedication ceremony, chief of public relations Dan Bigelow turns on all the tower's lights, but Roberts orders them shut off to reduce the load on the electrical system. Smoke is seen on the 81st floor, and the San Francisco Fire Department is summoned. Roberts and engineer Will Giddings go to that floor, where Giddings is fatally burned pushing a guard away from the fire. Roberts reports the fire to Duncan, who is courting Senator Gary Parker for an urban renewal contract and refuses to order an evacuation.

SFFD Chief Michael O'Halloran arrives and forces Duncan to evacuate the guests from the Promenade Room on the 135th floor. Simmons admits to Duncan that he cut corners to bring the project back under budget and suggests other subcontractors did likewise. Fire overtakes the express elevators, killing a group whose elevator stops on the engulfed 81st floor. Bigelow and his girlfriend Lorrie are killed when a separate fire traps them in the Duncan Enterprises offices on the 65th floor. Lisolette Mueller, a guest and resident of the tower being wooed by con man Harlee Claiborne, rushes to the 87th floor to check on a deaf mother and her two children. Security Chief Jernigan rescues the mother, but a ruptured gas line explodes, destroying the stairwell and preventing Roberts and the rest from following. They traverse the wreckage of the stairwell to reach a service elevator which takes them to the 134th floor, but the door to the Promenade Room is blocked with hardened cement. Roberts uses a ventilation shaft to reach the Promenade Room, while Lisolette and the children stay behind.

As firemen begin to bring the fire under control on floor 65, the electrical system fails, deactivating the passenger elevators; O'Halloran abseils down the elevator shaft to safety. As firemen ascend to free the blocked door at the Promenade Room, another explosion destroys part of the remaining stairwell, blocking the last means of escape from the upper floors. After the stuck door is freed, reuniting Lisolette and the children with Roberts and the others, Simmons makes a futile attempt to escape down the stairwell, but is blocked by flames and retreats. Meanwhile, Claiborne reveals his true identity and intentions to Lisolette, who says she doesn't care and still wants to be with him.

An attempt at a helicopter rescue fails when two women run up to the aircraft: the pilot tries to evade them and crashes, setting the roof ablaze. A Navy rescue team attach a breeches buoy between the Promenade Room and the roof of the adjacent 102-story Peerless Building, and rescue many guests, including Patty Simmons, Duncan's daughter. Roberts rigs a gravity brake on the scenic elevator, allowing one trip down for 12 people, including Roberts' fiancée Susan Franklin, Lisolette, and the children. An explosion near the 110th floor throws Lisolette from the elevator to her death and leaves the elevator hanging by a single cable. O'Halloran rescues the elevator with a Navy helicopter.
