Documentary which looks at a possible cure for people in long-term comas, such as Britons Joanne Douglas and Amy Pickard. Patients in South Africa were reported as waking 'as if a switch has been flicked' after the administration of a sleeping pill. Desperate to know more, both Amy and Joanne's families journey to South Africa to meet the patients who are being treated, wanting to know if this is just another false hope or if their daughters could really be reborn.
