Xanadu JR. follows the journey of a magical and beautiful Greek muse, Kira, who descends from the heavens of Mt. Olympus to Venice Beach, California, on a quest to inspire a struggling artist, Sonny, to achieve the greatest artistic creation of all time – the first Roller Disco. (Hey, it's 1980!) But, when Kira falls into forbidden love with the mortal Sonny, her jealous sisters take advantage of the situation, and chaos abounds.
