Lance Forrester is a dreamer. After a celebrated career as an astronaut and engineer, he and a friend build a secret spacecraft to seek their destinies in the stars. But his friend dies and Lance is diagnosed with terminal cancer. Desperate not to succumb to his fate, he convinces an acquaintance, ailing actress Sage Saint Claire, whom he hasn't seen since high school, to join him on his quest to reach an advanced alien civilization which can heal them both. Unfortunately, true life is not a Hollywood movie, as much as Sage might want it to be, and problems abound. Mistakes in the past have turned Sage into a bitter old woman, and she turns out to be a less-than-perfect traveling companion which no amount of optimism, youth, or good health can cure. Can these two intrepid octogenarians-turned-immortals overcome the emotional scars of their pasts and achieve true happiness, or are they doomed to suffer for their mistakes, no matter how far from Earth they go?
