Miranda is an unconventional woman: a tall, life-embracing, self-effacing clown, who's at her happiest amongst the wind-up teeth of her Joke Shop.

She's used her inheritance to buy a joke shop (much to her family's dismay), but lacking the organisational skills needed for retail - or anything else - Miranda has gone into partnership with Stevie, one of Britain's greatest humour vacuums.

Stevie mans the till for hours at a time whilst Miranda 'pops out' on regular, self-imposed challenges. Miranda is determined to suss out what it takes to be a girly girl, to deal with her outrageously embarrassing mother Penny in public places, to not look a complete idiot every time she meets the gorgeous Gary and to persuade other people to take life less seriously.
