As the sun begins to dim along with humankind's hope for the future, it's up to a desperate crew of eight astronauts to reach the dying star and reignite the fire that will bring life back to planet Earth in this tense psychological sci-fi thriller that re-teams 28 Days Later director Danny Boyle with writer Alex Garland and producer Andrew Macdonald. The skies are darkening, and the outlook for planet Earth is grim. Though the encroaching darkness at first seems unstoppable, scientists have concocted one desperate last-ditch plan to buy the human race a temporary reprieve from the grim future that looms just past the horizon. A crew of eight men and women has been given a nuclear device designed to literally reignite the sun and sent hurtling through infinity on the most crucial space mission ever attempted. Suddenly, as the crew loses radio contact with mission control, everything begins to fall apart. Now, in the farthest reaches of the galaxy, the men and women who may hold the key to ultimate survival find themselves not only struggling for their lives, but their sanity as well. Rose Byrne, Chris Evans, Cillian Murphy, and Michelle Yeoh star in a film that asks audiences just what would become of humankind if the sky suddenly went black.
