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.
Miranda isn't your average girly girl - at 6'1" Miranda gets called Sir once too often, much to the amusement of her childhood friend Stevie, who manages Miranda's joke shop.
And to top it all off, Miranda's mother Penny is disappointed that Miranda runs a joke shop rather than having a proper job.
Since Gary left for Hong Kong, and her chance at a relationship with him gone, Miranda has been watching telly all day in her pyjamas with a packet of biscuits for company.
She is eventually persuaded, by Stevie, to stop wallowing and move on, starting a new regime and become the new her.
She will get fit, lose weight and become the type of woman her boarding school nemesis Tilly, and hard to please mother, Penny, would be proud of... or will she?
