Dr. Alexander Stark is determined to have Skippy for his private zoo. When Matt Hammond refuses to sell at any price, Stark has two of his henchman steal the kangaroo and she begins a tense series of adventures to find her way home.

Matt Hammond's boss and a government Senator decide to sack him after it appears that Matt has run their car off the road and threatened them. It transpires that Dr. Stark has hired an actor to impersonate Matt Hammond in order to discredit him, but the whole scheme backfires and Dr. Stark has to honour the promise of a $10,000 donation to Waratah National Park.

Dr Stark sends an operative into the park to collect a rare ant-eater specimen using a special gas-emitting camera. Clancy stumbles across the collector and is temporarily paralysed by the device. Skippy returns an incriminating audio recording of the encounter back to the ranger HQ leading to the thief's capture and Clancy's safe return.
