S1, E1: Sonny Hammond is a Park Ranger. After an accident involving a dangerous helicopter rescue, he is sent to work in the city. He and his twin children Jerry and Louise (Lou) are unhappy at being cut off from the bush and most of all from their wonderful kangaroo Skippy. Skippy disappears from her usual bush haunts, pining for her lost family. Two of the Hammonds’ friends mount a search for her - Kate the vet, and Thel McGee, proprietor of Habitat, a small animal-based tourist attraction near the National Park. Kate and Thel, however, decide that only theHammond twins can help in the search. Skippy is found by Jerry and Lou, Sonny becomes a partner in Habitat, and the Hammonds are off to a new life.
