Four children stumble into the secret underground lair of a long-dead super-hero, the Silver Shadow. Defeated (and killed) by his arch-nemesis, The Crab, in the 1950s, the Silver Shadow lives on as a digital recording in his base's computer. Just as he convinces the four to take up his role as the city's defender, The Crab, now an old man in a retirement village, trains his grand-daughter to be his own successor.
As with other programs produced by the Australian Children's Television Foundation (ACTF), Legacy of the Silver Shadow concentrated strongly on questions of self-identity, peer pressure and conformity, and individualism.
