24 Hours in A&E

Niki, who's 34, is airlifted to St George's after crashing into another rider during a charity bike ride between London and Brighton. Race volunteers found him unconscious and unresponsive. It becomes obvious that Niki's memory has been affected by the impact as he struggles to recall details of the crash. Meanwhile, St George's staff try to contact Niki's wife Phil, who is almost 300 miles away at their home in the north east of England.
