Bigfoot and Gray had the fortunate opportunity to meet each other the day Gray crash-landed his flying saucer into Bigfoot's living room (which consisted of some hastily thrown together twigs and underbrush), just as he was sitting down to lunch (which also consisted of some hastily thrown together twigs and underbrush). But the crash did not go unnoticed, and now, agents of a super-secret government organization called the FBO are after them. Bigfoot and Gray must rely on their dim wits (and therein lies their plight) to avoid government capture in their new life on the run!
