Two agents of the mouse-run International Rescue Aid Society search for a little orphan girl kidnapped by sinister treasure hunters.

A lawless poacher wants to capture a majestic and rare golden eagle, so he kidnaps the boy who knows where to find the bird. Not to worry -- the Rescue Aid Society's top agents, heroic mice Miss Bianca and Bernard, fly to Australia to save the day. Accompanying the fearless duo are bumbling albatross Wilbur and local field operative Jake the Kangaroo Rat.
