One of them would kill to be a mother... Darkford General Hospital is deeply shaken when its star midwife, Sarah, is arrested for trying to steal a baby.

In the ensuing shock, midwives Erica and Sue rally to reassure Darkford's patients, including Leila - an expectant mother whose trust has been broken before.

Leila reluctantly accepts the hospital's support - after all, she isn't getting enough of that at home. But when Sarah is released from custody, Leila's paranoia escalates.

As her due date ticks closer and closer, Leila can't shake the feeling someone is watching her, and waiting. Everyone at Darkford wants the best for her child. But a mother's instinct is telling her that someone among them wants more from her... and will stop at nothing to take it.
