The Martian features Matt Damon as NASA astronaut Mark Watney, who with a six-member crew including commanding officer Jessica Chastain, is on a month-long science mission on the beautifully desolate surface of Mars. Of course, one month is only the planned duration of their stay on the surface; the deep space transit to and from Mars takes several hundred days each way, which becomes important later in the film.
We enter the story partway into the surface mission. The crew is collecting Martian soil samples when NASA sends them an urgent message about an impending storm. The storm is apparently so severe that the rocket which is supposed to lift the crew back into space at the end of their mission won’t survive the harsh winds on the ground. So the crew is forced to abort their surface mission and perform a hasty emergency launch. In the rush and confusion, Watney is left behind, presumed dead. All of this introductory material is completed in a very breezy few minutes, plunging us right into the survival story.More
