Episode list

The Poppels bid farewell to their friend Dr. Deighton, who leaves Adelaide to continue his profession in Gawler. Arthur's foot injury has not yet healed and he is therefore unable to resume work. His family has nearly run out of money, so they have no choice but to begin selling some of their goods in order to survive. Among these is "Snowflake," the sheep Lucy-May raised from lambhood. Lucy-May begs her father not to sell her, but he ultimately does so.

After being struck down by a runaway horse and cart on the loose, Lucy-May loses consciousness. She is taken in by the Princetons and nursed back to health by their doctor. Lucy-May has temporarily lost her memory due to the impact and cannot remember her name or residence. Arthur, concerned that her daughter has not returned home, sets out to search for her, joined by John and Little, the dingo.

The Poppels continue their search for Lucy-May but are unable to learn her whereabouts. Meanwhile, the Princetons bring Lucy-May to the Adelaide bridge, hoping that the sights will result familiar to her and help her remember. Their coach drives past the Poppels' house but Lucy-May does not recognize it. As long as the girl cannot remember her real name, Mrs. Princeton asks her permission to call her 'Emily', the name of her deceased daughter, much to the disapproval of Mr. Princeton.

Upon returning home from Gawler, where Arthur and Kate had hoped to find the missing Lucy-May, they run into Mr. Pettiwell. He is convinced that the Poppels want to purchase a farm owned by the Princetons, a property he himself is interested in. He visits Mr. Princeton, who firmly tells him that the property is not for sale. Mr. Pettiwell then spots Lucy-May but fails to recognize her as the Poppels' child. Mr. Princeton is concerned that his wife is becoming too attached to this unknown girl she insists on calling 'Emily.'

Arthur feels responsible for Lucy-May's disappearance and is tempted to begin drinking again. Ben and Clara comfort him and promise to help realize the family's dream of starting their own farm. Frank Princeton suggests placing an ad in the local newspaper to his wife, hoping to locate Lucy-May's family, and she reluctantly agrees. For his part, Ben also comes up with the idea of placing an ad in the newspaper. Meanwhile, Little continues his own search for his lost playmate.

Lucy-May grows increasingly frustrated at not remembering who she is. After a visit to the Marchioness of York, Lucy-May asks Mr. Princeton's permission to stop at the Adelaide bridge, where he first found her. She cannot, however, remember anything. Little, her beloved pet dingo, appears and is delighted to see her. When she slips out the term 'little' her memories come rushing back. Little returns to the Poppels, closely followed by the Princetons' coach bringing Lucy-May back to her family. Sylvia Princeton is broken-hearted at the loss of her 'Emily.'

With Lucy-May now safely home, the Poppels can make up for three sleep-less nights. Mr. Princeton arrives to bring Lucy-May the doll and dress Mrs. Princeton had bought for her, and invites both she and Kate to come visit them, since he would like to speak to their father. Meanwhile, Arthur is considering a job in the iron mining town of Mount Barker, so he, Mrs. Poppel, Kate, Lucy-May and Tob head over to see this place first hand. The children are not impressed by the humble appearance of the housing, but are thrilled by the sight of the many kangaroos roaming the area. They are quickly distressed by the sight of hunters pursuing the animals, however.

While chasing an orphaned kangaroo, Kate and Tob fall into a pit. After helping Tob out, Kate is frightened by a menacing sound that turns out to be a wombat, which Lucy-May then keeps as a pet. Clara is visited by Sylvia Princeton and learns that her husband is a part of the mining company in Mount Baker, where her father is seeking work. Shortly afterwards, Arthur and Lucy-May visit the Princetons' stately home, while Kate is forced to say home, much to her displeasure, as she is running a fever. Mr. Princeton asks Mr. Poppel that he consider working in his farm, while his wife still yearns for Lucy-May to stay with them.

Lucy-May tells a very curious Kate all about her visit to the Princetons', including her concern that Mrs. Princeton has become far too attached to her and still wishes she would take her deceased daughter's place. Arthur considers the possibility of working for Mr. Princeton but dislikes the idea of working at a farm that is not his. Lucy-May's new pet wombat wanders off and is killed by the wheel of Mr. Pettywell's coach, causing her enormous grief. Arthur visits Frank Princeton to formally refuse his offer, but changes his mind when he learns that if he does, the farm will be sold to Mr. Pettywell.

Frank Princeton arranges to bring the Poppels to visit what will become their new home: his farmland, where Arthur will be working for him. Kate is far too excited to sleep, while Lucy-May worries that the move will separate her family. The next day, the family is saddened when the Princetons' coachman informs them that the visit will be postponed since Mrs. Princeton is ill. While discussing the unfavorable current state of the farm, Mrs. Princeton urges her husband to give part of its land to the Poppels. Shortly afterwards, Lucy-May overhears Frank Princeton tell her parents that he and his wife wish to adopt her as their own.

Mr. Princeton offers the Poppels a piece of his land in exchange for being allowed to adopt Lucy-May. Arthur refuses the offer, firmly stating that they would not part with any of their children for anything. Hurt by the proposal, Mr. Poppel further declines working for the Princetons and finds work in construction instead. The Poppels finally celebrate Clara's marriage, even if the happy occasion is partly overshadowed by the family's realization that the dreams that brought them to Australia may never be fulfilled. Concerned for her family, Lucy-May visits Mr. Princeton and asks to be taken in as he and Sylvia's daughter.

The Princetons are overjoyed when Lucy-May agrees to be their daughter, but they are quick to realize that this is not what the girl wants. Lucy-May is concerned that her father has again turned to alcohol, and wishes the Princetons to grant him the land he so desperately desires. Sylvia Princeton apologizes for her selfishness and tells the girl that because she loves her she wants her to be happy. The couple offer to sell the Poppels a part of their land property; they'll pay it off by selling their current home and through Arthur's work at Frank's farm over the years. The property has two houses where Clara and her husband John can live, so the Popple family will stay united. Arthur is delighted and accepts the offer. Following some light showers, the family can now see their dreams be fulfilled at the end of the southern rainbow.
