Danny is a 10-year-old boy with no special powers. He travels on an airship between Earth and a distant civilization and is frustrated with being dismissed as an outcast in both worlds. While on an exploratory mission, a wicked emperor attacks the airship and kidnaps Danny's parents. Danny must join forces with his friends across seven continents in a desperate chase across space and time to save his family. They try to fend off the angry robots, ghastly warriors, and bent-nose mobsters as they unravel clues to find the portal to the sorcerer's ice castle of fire.
