Tommy Tricker and the Stamp Traveller

When the aptly named Tommy Tricker (Anthony Rogers) tricks sensitive young Ralph James (Lucas Evans) into swapping away an important stamp, it triggers a series of events that leads to a fantastical adventure. Soon Ralph and his sister, Nancy (Jill Stanley), gain the ability to shrink to a tiny size and travel the globe on postage stamps. Eventually, Ralph and Nancy wind up in Australia, where a rare stamp collection factors into their magical journey.
