We last seen Sheridan Smith as Cilla Black in the three-part drama series about the late star's rise to fame, a performance which earned Smith a National Television Award this year. She returns to the screen now for this one-off drama based on the blog and book by Lisa Lynch, which is an account of her life after being diagnosed with breast cancer. Lisa was just 28-years-old and recently married when she discovered she had breast cancer. Determined not to let the disease beat her she decided to write about her experience, completely unaware of the effect this would have on her life and so many others.
