Project Hail Mary 🎥 2026 Movie Info

Plot Summary

In 2032, Ryland Grace awakens from an induced coma on an interstellar spacecraft. Initially erratic and amnesic, Grace learns that he is the sole survivor of the three-person crew on a spaceship light-years from Earth, which embarked on its journey to the Tau Ceti system over ten years earlier. Throughout various flashbacks, Grace remembers that he is an American middle school science teacher and former molecular biologist. Years ago, scientists observe an infrared line, named the “Petrova Line”, forming from the Sun to Venus.

They discover a microorganism, termed “astrophage”, proliferating on the Sun’s surface, causing it to dim, and predict it will cause catastrophic global cooling within 30 years; Government agent Eva Stratt recruits Grace and other scientists to study it. Grace discovers that astrophages are single-celled organisms impenetrable to electromagnetic radiation. The astrophage breeds on Venus, using the planet’s atmospheric carbon dioxide and energy and hydrogen from the Sun. The Petrova line is created by astrophage propulsive emissions as they migrate between the Sun and Venus. Their emissions can be used to construct an incredibly efficient spacecraft engine.

The astrophages have infected other stars within Earth’s solar neighborhood; Stratt discloses Project Hail Mary, an international effort to send a crew to Tau Ceti, the only undimmed nearby star, to investigate. It is a suicide mission; the Hail Mary spacecraft can carry only enough astrophage fuel for a one-way trip, but the crew’s research will be sent back to Earth via probes. When an astrophage explosion kills the crew’s scientist and his backup, with no time to train a replacement, Stratt asks Grace to take his place. When he refuses on the basis that he is untrained, Stratt has him drugged and put aboard the ship. In the present, as Grace approaches Tau Ceti, an alien spacecraft docks with the Hail Mary.
