Presumed dead, Commander Lewis (Jessica Chastain) has no choice but to leave him behind and head back to Earth. The injured Watney wakes to find himself alone on Mars, with the prospect of having to live several years on the planet before the next ship come for its scheduled mission. Can Watney survive the harsh, alien landscape and the more alienating loneliness? How will he be saved? With an unstoppable self belief and scientific knowhow, Watney uses his expertise in botany to survive and grow food to become the first Martian colonist.
