Scrapland is going broke. As over half the country's budget pays for the upkeep of King Leadfoot and his Knights, the downsizing options are limited an obvious. Forced into early retirement, Knight Rusty is looking for a new job. In the basement of his castle he meets a ghost who shows him the unfinished work of his father, an inventor in Scrapland's former days. When power crazed police chiefs take over the country, Rusty finally accepts that he must do what he is created for: Protect Scrapland and complete his Father's vision.
