The Dark Princess is up to big-time mischief: snatching for herself Spectra, the universe's sole source of light. Without Spectra in its rightful place, all will be plunged into gloom and dreariness - unless Rainbow Brite and her friends can defeat the princess in this fantastic adventure! Set in an imagination-enhancing cosmos of enchanted worlds, spunky Rainbow Brite, her magical horse Starlite, heroic spaceboy Krys, spritely Twink, young earthling Brian, venerable sage Orin, and other amazing Hallmark characters confront evil by using colour, magic, cleverness and joy as ammunition.
