It will take the Starship Avalon spacecraft 120 years to reach a new planet, so the 5,000 people who will colonize the new planet are all put into hibernation. A malfunction causes two of the hibernation pods to stop working, so Aurora and Jim wake up 90 years before they reach their destination. Faced with spending the rest of their lives alone on the spacecraft, a romance starts to blossom between the two. Their newfound life together is interrupted when they discover that a problem may threaten the entire spacecraft, and only Jim and Aurora are capable of stopping it.
