This episode explores the value of freedom, and what happens when it's taken away. Michelle, who's 49, is rushed to St George's after having a collision with a car while riding her motorbike on a dual carriageway. Emergency care nurse Lee, who also has a passion for motorbikes, asks to be the nurse in charge of her care. Michelle grew up in South Africa during the Apartheid era, but when her marriage fell apart she made a leap of faith and moved to Britain. Gradually she started to find her feet and took up riding a motorbike, finding the feeling of freedom 'absolutely awesome'.
