When Worlds Collide Plot Summary

What happens in When Worlds Collide from start to finish, spoilers included, with a timeline of 12 key events. The opening is below; the full summary is a 3-minute read.

Spoilers ahead

Opening with Genesis quotes that set a grim frame, the film follows David Randall, a pilot who carries top-secret photographs from South African astronomer Dr. Emery Bronson Hayden Rorke to the United States. There, Dr. Cole Hendron is confronted by the alarming news: Bronson has detected a rogue star named Bellus and an Earth-sized neighbor planet named Zyra hurtling toward collision with Earth. Hendron, aided by his daughter, Joyce Hendron Barbara Rush, concludes that time is dangerously short—roughly eight months until Zyra’s close pass and then Bellus’s following impact would end civilization as we know it. The stakes are existential, and Hendron pleads for a plan to save humanity by building arks large enough to ferry a select group to Zyra in a faint hope of survival.
