Three cadets from the Academy Of Galactic Exploration and a Pyrian princess are in a distant sector of the galaxy, when they encounter the warfaring Triad, who had destroyed Pyrus and other planets. Unable to match the Triad's firepower in their ship, they have to rely on stealth and speed to avoid their clutches. They must warn Earth, but dare not lead the Triad to their homeworld.

Hypernauts is a proof of concept show produced by Foundation Imaging and Netter Digital Entertainment. To further prove that the computer-generated imagery and visual effects created in Babylon 5 were easily applied to other venues, the Hypernauts were born. ABC purchased thirteen episodes of the show from DIC Productions L.P., eight of which ran on Saturday mornings for a single season in 1996 at 10:00 AM. ABC decided not to pick up the series for a second season, and did not air the five remaining episodes. The show was created and produced by Ron Thornton and Douglas Netter, its executive story editor was Christy Marx who also wrote four episodes. Marx had previously written for both Babylon 5 and Captain Power. Another series writer was Katherine Lawrence who was nominated for a Writers Guild of America Award due to her script for Ice Bound.
