Dr. Shrinker, an evil scientist, lived on an island with his assistant, Hugo (Billy Barty, "UHF"). The pair would work on various inventions, including a shrinking machine. Brad, BJ and her brother, Gordie, are three teenagers who crash land on the island. Dr. Shrinker decides to use the three teens as guinea pigs to test his shrinking ray, but they manage to escape from Dr. Shrinker's lab. Dr. Shrinker spends the rest of the series thinking up of new ways to capture the teens.

    The series aired on ABC, from 9/11/76 - 9/3/77, as part of Sid and Marty Krofft's "The Krofft Supershow." 16 fifteen minute installments were produced, and the show would air in rotation with other classics like "Wonder Bug," "Electra Woman and Dyna Girl" and "Magic Mondo," as well as skits from "Supershow" hosts Kaptain Kool and the Kongs.
