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.

Deke, a runaway orphan from a boy's home, is arrested when he prevents Art Finney, a trainer for a wealthy California dog breeder, Andrew Garrett, from shooting "Rock", a renegade English setter and alleged animal killer. Garrett has Deke remanded to his custody and gives him a job assisting the (highly) resentful Finney and also working with "Rock", whom Deke insists has the makings of a fine hunting dog. The trainer and owner/breeder don't think so, but they accept the word and non-experience of a 17-year-old orphan?
