Old familiar faces return to the Crossing when a party is held after Harry Cooper's diary is found. Things don't run quite as smoothly as planned though when George Baxter, who believes he owns a dairy as a consequence of what was written in the diary, crashes in to the bus carrying Chris. Tom makes it back from Africa and Emma arrives, with out Sam, but with two children in tow. When Geoff discovers that Baxter is not entitled to the diary, he decides to return ownership to the town. DJ returns from Greece and flirts with Penny, much to Steve's annoyance. It is announced that Chris will go back with Tom to Africa.
