An elite unit of soldiers known as the Sky Commanders, "Protectors of the High Frontier," battle General Plague's army from their cliche world domination plot. The Sky Commanders include General Mike Summit [Bob Ridgely], Commander Rex "Cutter" Kling [William Windom], Commander Cliff "Books" Baxter [Richard Doyle], Commander Pete "Kodiak" Crane [Soon-Teck Oh ], Commander Jack "Spider" Reily [Tristan Rogers], and Commander R.J. Scott [Darryl Hickman] - able to transverse long distances with the help of their specialized backbacks that had grappling and cablecar abilities.

The Commanders were stationed at a base called Vector Command, and moved along cables suspended by grappling hook devices, or hover vehicles. Plague's own brand of raiders had similar backpacks, and included right-hand man Raider Rath [Paul Eiding], Mordax [Dick Gautier], and Kreeg [Charlie Adler].

Narrator: Deep in the South Pacific, a tumultuous and untamed new continent has erupted, spawned by a highly unstable new element, known as Pheta-7. If this powerful new element could be controlled, whoever possessed it would be the undisputed ruler of the world.

One man, General Lucas Plague, is determined to hold that title. And it's up to a rugged team of mountaineering experts, lead by commander Mike Summit, to stop him. Employing revolutionary new gravity-lock and laser-cable technology to traverse the ever-changing terrain of the High Frontier, Mike Summit's Sky Commanders, and General Plague's Raiders, are locked in mortal combat, with the fate of the entire world hanging in the balance!
