Eileen and Bill are marooned in a loveless marriage, both hurt by the estrangement of their youngest child, Darren. They are closer -- if only in proximity -- to their three daughters: eldest sister Debbie is a hard-partying hairdresser, separated from her ne'er-do-well husband Dan and raising their son Jack; Nadia is a lonely waitress who searches for love through the personals, which is how she meets Tim; and Molly, who's in a committed relationship with Eddie, is expecting their first child. All will find the foundations of their relationships shifting in surprising, ruefully funny and emotional ways during the boisterous annual "Bonfire Night" in South London.
