Jock and Siobhán's daughter Star is turning six and a birthday party is being organised. Orla Walsh however is having her kitchen redone, and asks Mairéad to host the party.

It's the most wonderful time of the year, and Mairéad, Sgt Healy and Conor are preparing for the imminent new arrival, with Conor wanting only the best for his mother. Conor is still a novice at domestic housework, including washing, so Mairéad decides to give him lessons, clearing out his wash basket thoroughly – only to discover a handgun in the basket.
