Dr. Ryan Stone (Oscar winner Sandra Bullock) is a brilliant engineer on her first shuttle mission with veteran astronaut Matt Kowalski (Oscar winner George Clooney). On a seemingly routine spacewalk, disaster strikes. The shuttle is destroyed, leaving Stone and Kowalski completely alone, tethered to nothing but each other and spiraling out into the darkness. As fear turns to panic, every gulp of air eats away at what little oxygen is left. But the only way home may be to go farther out into the terrifying expanse of space.
