This series is a spin-off from the long running BBC medical drama "Casualty". Set in the same hospital as its sister series, this show follows the everyday lives, professional and personal, of the doctors, nurses and patients who find themselves, for various reasons, in the wards of Holby City General Hospital.
Casualty, styled as CASUAL+Y, is the longest running emergency medical drama series in the world, and the second-longest-running medical drama in the world behind America's General Hospital.
