When ‘Lady’ Sandra Abbott (Imelda Staunton) discovers that her husband of forty years is having an affair with her best friend, she seeks refuge 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 and she reluctantly lets Bif drag her along to her community dance class, where gradually she starts finding her feet... and romance. In this hilarious and heart-warming modern comedy, a colourful group of defiant and energetic ‘baby boomers’ show Sandra that retirement is only the beginning, and that divorce might just give her a whole new lease of life - and love.
