David Tennant's new British comedy drama, There She Goes, premieres tonight on BBC Four at 10pm.

The five part series centres on a severely learning disabled nine year-old girl Rosie (Miley Locke), her dad Simon (David Tennant), mum Emily (Jessica Hynes) and brother Ben (Edan Hayhurst).All the stories and characters are drawn from the real life experience of writer Shaun Pye, whose daughter was born in 2006 with an extremely rare and to date undiagnosed chromosomal disorder. Each episode shines a light on day to day life with Rosie - unique experiences from simply trying to take her to the park to trying to explain that every day isn’t her birthday. A second timeline set in 2006 shows the effect having a severely disabled child had on the family unit, how it threatened to disintegrate but ultimately brought them even closer.

Episode One - A Day In The Life Of Rosie Yates
Rosie is a nine year-old girl with a severe learning disability, the result of an undiagnosed chromosomal disorder. She lives with her dad Simon, mum Emily and brother Ben.
It’s a typical Saturday for the family, one which revolves around trying to get Rosie to do simple things - go to the park for some fresh air, eat her lunch, go to bed. Rosie leaves a trail of destruction in her wake, ramping up Simon’s stress - in his short-sighted attempts to get her to go to sleep too early, he only makes things worse.
An earlier timeline shows how Simon and Emily first confront the inescapable truth that something is wrong with their baby daughter.
