Television drama focusing on the pain and confusion one woman faces after waking from a 18-year long coma, to a world where nothing is the same. 36-year-old Kate (Genevieve O'Reilly) has spent half her life lying motionless in her childhood bedroom. When she awakens from her coma, she discovers that everything around her has changed: her parents Eileen (Geraldine James) and Toby (Robert Pugh) look like her grandparents, her friends have succumbed to the jobs and the families they swore they'd never have, and her boyfriend Pete (Mark Bazeley) is in love with someone else. Her miraculous re-awakening sends shock waves around her family and friends to whom Kate is a reminder of their own lost youth. Her initial re-emergence into society is a painful one, but as she embarks on an accelerated rites of passage, Kate learns to deal with her extraordinary situation and attempts to make up for her lost time by living life to the full.
