Three astronauts is in space. When Ryan Stone(Sandra Bullock) and Sheriff are repairing the Hubble Telescope, Matt Kowalski(George Clooney), a veteran astronout and the commander of the space shutter Explorer is giving them company. He continuously talks to Ryan in between explorer captain and mission control. Now reports are received that space debris are coming forth towards them, they have to leave the mission there. All dies in the shuttle. But, Ryan and Kowalski manage to survive in this disastrous situation. They reach near ISS where Matt releases himself in the space to save Ryan. The sole survivor of STS-157 Ryan have to return to the earth using Shenzhou space craft.

There is hardly a transition effect in this film. Which depict that 'How' is so important in this film. Must say that the film has a great continuity and becomes a one character movie in the end. To portray the space director uses reflections, lights, sound everything. Kowalski once says to Ryan, "You gotta admit one thing, can't beat the view".
