A house materializes in the woods during a storm, and three kids don't question it. They just step inside. What follows is 52 episodes of pure forward momentum, no home base, no safe return, just a flying house and whatever comes next. The show trusts its premise enough to skip the explanation entirely. That's the entire appeal: a group of kids in motion, discovering the world as it comes, no heavy lifting required.

Justin, Angela and Corkey are in the middle of a game of hide and seek in the woods when a sudden storm drives them to shelter in a house Justin has never noticed before. Inside they meet a robot called SIR and his owner, Professor Bumble, who shows them his proudest invention: a time machine. When the professor tries to power it with a kite in the storm, the experiment goes wrong and the whole house is hurled into the past. As the children search for a way home, the professor's mistakes keep them traveling, and they end up witnessing events from the New Testament, from the birth of John the Baptist to the rise of the Apostle Paul.
