- * The Towering Inferno * -

Architect Doug Roberts returns to San Francisco for the dedication of The Glass Tower, a mixed-use skyscraper that he designed for developer James Duncan. The tower, 1,688 feet (515 m) tall and 138 stories, is the world's tallest building. During testing, an electrical short-circuit starts a fire in a storage room on the 81st floor 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. Roberts confronts Simmons, who 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.
