Margaret and the Wheelers help the Brights move into a brand-new family home, architecturally designed by Danny. The uber modern-verging-on-brutalist house leaves them all a bit bemused, but Bess feels particularly uncomfortable in the cavernous concrete rooms. Meanwhile Brianna has found love and is eager to cement her relationship with her new fiancé, Younis.

When a shop owner spots Kayne's artwork, she commissions him to paint his designs on her expensive homewares store but has no plans to pay him. While Margaret wants to stop Kayne being exploited, Bess grapples with a gift from Julie, a fake Fendi bag, and Danny struggles to accept that his local coffee supplier has copied his favorite designer shirt to make its uniform—for a fraction of the price.

Bess is alarmed to discover that Julie has a sister, despite Julie telling all the children that her sister was dead. Julie forbids the family from contacting her, but Bess, desperate not to have any more secret relatives, enlists Brianna, Amber, and Margaret to help her investigate. Danny takes Oscar away to an architects' conference, where his special role as guest speaker is compromised.

Amber is appalled when Shawn arrives home with his new and highly alternative girlfriend, Ashley. Squeezed tight in the bungalow, Amber struggles to find space, not just with Shawn, but with the rest of the family, too. Bess is distressed when Edwina announces she wants to study medicine after meeting an inspirational female surgeon, despite never before expressing interest in her mother"s field.

Amber and Shawn settle into their new home, but when Shawn announces he is dropping out of school, Amber despairs. She turns to Shawn's school principal, Evan, for help, who, despite being world-weary and cynical, delivers salvation in an unexpected manner. A knee operation forces Julie out of the Top Fuel comp, so Kayne steps up to drive for Team Wheeler.

Bess vies for a position on the Board of the International Women of Medicine by attending a charity Mothers' Day luncheon. Eager to celebrate the day with Bess, both Margaret and Julie join her, but the concept of Bess having "two mothers" is misconstrued, to Margaret's horror. Amber manages to keep her blossoming romance with Evan private until Wayne and the family discover them together.

When Edwina's rowing scull is woefully underprepared for the interschool regatta, she begs Brianna to step in as coach, who accepts the challenge with gusto. To cheer them on, the Wheelers join Bess up at the Murray River, replete with jet skis and giant tires. Evan takes the opportunity to give Amber his dad's vintage speed boat, but he is taken aback when she seems unhappy with his gift.

Exhausted by Margaret and Julie fighting over her, Bess plans to spend Christmas in New York with Danny and the kids. Telling Margaret is challenging, but it's telling Julie that proves impossible, as she faces her first Christmas without Amber and Brianna. A heartbroken Julie is not even consoled by Wayne and Kayne's promise to make their Christmas lights display the best on the street this year.
