Kapp Adams--a bionic astronaut forced into early retirement after a crash landing--spends his days drinking and womanizing in Las Vegas. Jaded by life on Earth, he jumps at the opportunity to return to space and soon embarks on the mission of a lifetime--to investigate a strange object discovered on the Martian moon Phobos. Upon waking from stasis eight months into the mission, Kapp discovers that all is not right onboard. From system failures to sabotage, he and the crew must conquer the dangers of outer space to stay alive and complete their mission. Hopelessly stranded, they choose to risk everything for a chance to get back home. But returning to Earth isn't the biggest challenge they face...it's what they encounter when they arrive.
