The series continues with a touching episode dedicated to love, from the concerned parents of an unresponsive child to the dedicated sisters of a 52-year-old with Down's syndrome.

It's a busy day at King's, as 400 patients are treated in 24 hours. Peggy, who's 85, comes in with her doting husband, and 25-year-old Ben's swollen finger is more serious than he realises.
