Kath Day Knight, [Jane Turner], and her partner Kel Knight, [Glenn Robbins], return from the Da Vinci Code European tour and plunge into two frantic weeks of Christmas preparations. Their home becomes a crowded stage for family dynamics, old grievances, and the constant push to keep the holiday spirit intact as the calendar ticks down to Christmas Day.
Kim Craig, [Gina Riley], uncovers Brett Craig’s ongoing affair with his boss, Kelly, [Peta Brady], igniting tension that ripples through every plan and conversation. Brett, [Peter Rowsthorn], retreats to the Buckingham Motel, leaving Kim to decide how much of his betrayal she’s willing to forgive while managing the fragile balance of their marriage and the season’s pressure.
Sharon Strzelecki, [Magda Szubanski], ventures into online romance and becomes engaged to Marriat, [Jeremy Kewley], only to face a devastating revelation: he does not exist and is nothing more than a blog. The heartbreak recalibrates Sharon’s hopes as she navigates the holiday period with surprising prudence and resolve.
Kath and Kel step into the spotlight as backup dancers for Michael Bublé, [Michael Bublé], at Carols by Candlelight in Melbourne. The festive glow of the performance becomes tinged with rivalry and insecurity, as Kath’s warmth clashes with Kel’s protective jealousy. The moment escalates when Kel’s anger erupts mid-show, and he strikes out against the star, prompting a tense reckoning about trust and boundaries. Kath’s blunt, caregiving instinct surfaces as she tells him not to bother coming home if he can’t keep his temper in check, sending Kel to the Buckingham Motel to cool off.
Yet Christmas magic and forgiveness slowly reclaim the season. Kath and Kel mend the rift, with Kath embracing the possibility of reconciliation as they prepare to celebrate together again. The balance of love, loyalty, and the long shadow of past mistakes threads through their days, testing their capacity to choose each other over the chaos that surrounds them.
Meanwhile, a string of strange messages arrives from John Monk, [Barry Humphries], the albino figure who runs the Da Vinci Code tour, including a cryptic line: “44 Euros.” His unexpected correspondence heightens the sense that danger might be near, even as curiosity stirs about what he wants with them.
John Monk then appears at their home, and Kel’s instinctive fear flares—he imagines the worst. Yet Monk’s visit veers away from menace and toward opportunity, as he proposes a franchise that could redefine their future and give them a new path to ride out the holidays’ uncertainties.
The story closes with an epilogue that hints at fresh beginnings: Kath’s first day as a tour guide on the Da Vinci Code 2 tour, a playful spark of adventure with the simple, inviting line, G'day Leonardo.
