Description: When ‘Lady’ Sandra Abbott (Imelda Staunton) discovers that her husband of forty years (John Sessions) is having an affair with her best friend (Josie Lawrence) she seeks refuge in London with her estranged, older sister Bif (Celia Imrie). The two could not be more different — Sandra is a fish out of water next to her outspoken, serial dating, free-spirited sibling. But different is just what Sandra needs at the moment, and she reluctantly lets Bif drag her along to a community dance class, where gradually she starts finding her feet and romance as she meets her sister’s friends, Charlie (Timothy Spall), Jackie (Joanna Lumley) and Ted (David Hayman).
