Fifty years from now, the sun is dying, and mankind is dying with it. Our last hope: a spaceship and a crew of eight men and women. They carry a device which will breathe new life into the star, but deep into their voyage their mission starts to unravel. There is an accident, a fatal mistake and a distress beacon from a spaceship that disappeared seven years earlier. Soon the crew is fighting not only for their lives but their sanity.
