Ross Bodine and Frank Post are cowhands on Walt Buckman's R-Bar-R ranch. Bodine is older and broods a bit about how he will get along when he's too old to cowboy. Post is young and rambunctious and ambitious for a better life than wrangling cows. When one of their fellow cowboys is killed in a corral accident, Post suggests a way into a better life for himself and his friend: robbing a bank. Bodine reluctantly joins in the plan and the two contrive to rob the local bank. They make good their escape initially, but Walt Buckman and his two sons, John and Paul, are incensed at this betrayal by their own trusted employees. John and Paul set out to bring Bodine and Post to justice.

Set fifteen years in the then-future year 1983, the series tells the tale of the crew and passengers of a sub-orbital transport ship named Spindrift. In the pilot episode, the Spindrift is en route from Los Angeles to London, on an ultra-fast sub-orbital flight. Just beyond Earth's boundary with space, the Spindrift encounters a magnetic space storm, and is dragged through a space warp to a mysterious planet where everything is twelve times larger than on Earth, whose inhabitants the Earthlings nickname "the Giants". The Spindrift crash-lands, and the damage renders it inoperable.
