Fifteen-year-old Kate and her two younger siblings, Nicholas and Sarah, are accidentally zapped inside Kate's current video-gaming obsession: Pirate Islands, a swashbuckling action-adventure game. Now the children--and the island's existing population of castaway children, led by the fearless Mars--must battle the fearsome Captain Blackheart if they wish to get back to their own world.
The program is structured around the generic conventions of video gaming: the protagonists must find a powerful object (the Golden Idol) in order to exit the game; the islands contain 'power ups', namely a jet-pack and magic boots, that give the protagonists super-human powers; and the location is divided into several distinct environments that the protagonists can explore (Castaway Island, Haunted Island, Plant Island, Main Island, and Secret Island).
The program has never been released on DVD in its entirety, but was cut down and released as two films.
