Project Hail Mary

Science teacher Ryland Grace (Ryan Gosling) wakes up on a spaceship light years from home with no recollection of who he is or how he got there. As his memory returns he uncovers his mission: solve the riddle of a mysterious substance that is causing the sun to die out. He must rely on his scientific knowledge and unorthodox ideas to save Earth from extinction — and an unexpected friendship suggests he may not have to do it alone.
