The eighth series kicks off with a Chatsworth Estate party, and it's not just any party - it's Frank's stag night. He's getting married to the love of his life, his romantic narcoleptic librarian third bride-to-be, Libby. Then, as the clock strikes midnight, Frank disappears. The mystery of Frank's whereabouts is a veritable magical mystery tour into the previously unexplored outer-limits of Frank's drink and drug-addled mind. With Frank missing, a dark cloud spoils the party spirit when a previous Mrs Gallagher returns. Meanwhile at the Maguires, Mimi is back in the nest with her surprise new baby Cilia, with whom Micky discovers his talent as a surrogate father-but the question remains, who's the Daddy? Nestled in between the Gallaghers and the Maguires is a new family: home-brewing fun and firey housewife Avril Powell and mild-mannered, until he's had a drink, trainee teacher Jackson Powell, plus their chronically, irretrievably thick, but gorgeous teenage daughter Letitia.
