The RTS award-winning documentary series returns for a seventeenth series following patients treated in the same 24-hour period at St George’s.

The hospital has one of the busiest A&E departments in Britain – under more pressure than ever. It’s a place where stories of life, love and loss unfold every day.

This episode – Do the right thing – features three patients who are seen at St George’s Emergency Department within a 24 hour period.

Mark, a 35-year-old long-term resident at a neurological hospital, is rushed to St George’s struggling to breathe, and his devoted parents are with him as doctors attempt to get to the bottom of his symptoms.

Three-year-old Thomas is brought in with a high temperature by his parents, who are concerned as he was born with an extremely rare blood condition that meant he needed a full blood exchange when he was less than 24 hours old.

Katrina, a 27-year-old Tube Driver, comes to St George’s after injuring her knee.
