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 begins to uncover his mission:
solve the riddle of the mysterious substance causing
the sun to die out. He must call on his scientific
knowledge and unorthodox ideas to save everything
on Earth from extinction… but an unexpected
friendship means he may not have to do it alone.
