Aileen's first communion is looming. Brenda, the matriarch, has a lot to deal with. She must play nice with her demanding auntie Nancy, a lazy husband with a penchant for gambling, a hapless teenage son, Connor, and her eldest daughter Clare, nursing the mother of all hangovers alongside her best friend, Marty. But it’s all worth it to see her youngest child, Aileen, in her new suit. Sort of. As preparations are in full swing throughout the episode, Paddy has bet the family holiday fund on a long shot of a greyhound who’s seen better days.
