An ordinary man wakes up alone on a spacecraft with no memory of who he is or how he got there. As fragments of his past slowly return, he realizes he’s humanity’s last hope. Ryland Grace (Ryan Gosling), a middle-school science teacher turned reluctant astronaut, has been sent on a desperate mission to a distant star to solve a cosmic mystery that threatens to extinguish life on Earth.
Armed with ingenuity, humor, and the power of science, Grace must unravel the cause of a dying sun and find a solution before time runs out for billions back home.
