When someone tries to steal a newborn from Darkford General Hospital, everyone is horrified. Even more so when evidence suggests it was one of the midwives ...

Katie, Erica and Sue are used to being heroes, not villains, as colleagues on the labour ward, so when one of them is arrested, the others must protect and reassure the pregnant women in their care that the danger has passed.
