Stevie attempts to stop Miranda spending all time in her pyjamas eating biscuits following Gary's departure to Hong Kong. Miranda eventually decides that the time is right to move on with her life and she deices to become the new Miranda, getting fit, losing weight and transforming into the type of woman mother and Tilly would be proud of. Miranda takes a shine to Gary's replacement but is surprised when Gary makes a sudden return.
The series is based on the radio show, Miranda Hart's Joke Shop which is based on Miranda Hart's semi-autobiographical writing. Miranda is a constant let down to her mother and she finds it hard to fit in. Miranda runs a joke shop and employs her old friend Stevie.
It doesn't matter what Miranda attempts in life, whether it's dating or simply dealing with her overbearing mother, she always seems to fall flat, quite literally.
