The series is set over a three-day family reunion of considerably more than a hundred guests, that draws together the extended branches of the Symon family. Raymond Symon (Michael Gambon) reluctantly attends with his wife Esther (Jill Baker) and son Daniel (Matthew Macfadyen), who was not aware of the sprawl of his extended family because of his father Lionel's (Jay Simon) estrangement from his relatives. The stories Daniel learns about his family's past are episodic and non-linear, from his mysterious presence in a photograph taken at a children's party that he can't remember attending, to the wartime experiences of three distant elderly cousins. An important plot strand concentrates on a rift between two cousins (Claire Skinner and Toby Stephens) and their aunt (Lindsay Duncan) that has grown since the sudden death of the cousins' brother and Daniel's attempts to reunite the trio. An early incident of Raymond suffering a stroke while giving a withering speech to the reunion-goers and his subsequent bedridden state force him to appreciate the character of relatives that reflect his. Poliakoff's use of old photographs to unlock the intricacies of individuals' lives is prolific. (fonte: Wikipedia)
