Miranda (Miranda Hart) is 6 feet 1 inch (1.85 m) tall and gets called 'Sir' once too often. She has never fit in with her old boarding school friends, Tilly (Sally Phillips) and Fanny (Katy Wix), and finds social situations awkward, especially around men. She is a constant disappointment to her mother Penny (Patricia Hodge), who is desperate for her to get a proper job and a husband. Although Miranda owns and lives above her own joke shop, she lacks any real capacity for business, so it is managed by her childhood friend Stevie Sutton (Sarah Hadland). The restaurant next door is run by Clive (James Holmes), who also works as a waiter. He has employed a chef - Gary Preston (Tom Ellis), a university friend whom Miranda fancies. The various episodes revolve around this set-up.
