Space Station 76 is a refueling satellite near an alternate-reality Earth, circa 1976. Jessica arrives to serve as the station's new first mate. While she narrates a piece about how she likes the predictability of asteroids, some placidly drifting asteroids are shown colliding in chain-reaction fashion. While at first the station appears normal and the people friendly, Jessica soon discovers that the people on board have issues due to the isolation and stress of being cooped up with one another in a relatively small space far from Earth. This is in addition the usual problems people struggle with, such as infidelity, loneliness, depression, and drug abuse. She tries to make friends and fit in, but, unable to connect meaningfully with anyone, she becomes lonely. She's baffled and disillusioned by the stiff and irritable Captain Glenn, who harbors secrets of his own. She finds herself drawn to Ted, a lonely, married crewman, and his 7 year-old daughter, Sunshine. Ted yearns to reconnect with his unhappy, medicated wife, Misty, but she's too far gone to respond and is driving him away. His daughter Sunshine contends with her unhappy, mentally ill mother and her own isolation issues. Events finally come to a head at a Christmas party when a rapidly unhinging Misty decides everyone needs to play the "Truth Game." Just when it seems like everything's falling apart, a celestial event shakes everyone to their core, reminding them what their real priorities in life should be. 虽然基本动力是女主的‘孤独’。。。 在未来的某一个时代，人类已经可以去很多星球居住，有一天忽然发生了意外，星球之间出现了碰撞，人们需要马上解决这个问题，因为它导致了人类的正常生活无法继续进行。
