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.

At Oceanfront High School, female students are being targeted by an unknown serial killer. Meanwhile, a married teacher hides his flings with nubile students, and an awkward male is frustrated by the plethora of uninhibited freewheeling young girls.

Given the chance to live in a simulated underwater home for a month, a scientist convinces his family to take advantage of the offer. Once the family agrees to move in, underwater mayhem occurs!

The film is 15 minutes in length and acts as both an introduction and a sample from the controversial John Herbert play Fortune and Men's Eyes, performed at the Coronet Theater in L.A. in 1969. The play was directed by Sal Mineo, who also rewrote and reshaped the play a bit. It follows Smitty, a young man sentenced to six months in prison for marijuana possession who eventually becomes the sexual subordinate of another inmate, Rocky.
