When 'Lady' Sandra Abbott (Imelda Staunton) discovers that her husband is having an affair, she seeks refuge with her estranged, bohemian sister Bif (Celia Imrie). As a fish out of water, Sandra is at odds with her sister's free-spirited lifestyle, until she is persuaded to join Bif's dance class, where Bif and her friends Charlie (Timothy Spall), Jackie (Joanna Lumley) and Ted (David Hayman) show Sandra that retirement is in fact only the beginning, and that divorce might just give her a whole new lease of life and love.
