The Replacement

When successful architect Ellen (Morven Christie, Grantchester) gets pregnant, she arranges for Paula (Vicky McClure, Line of Duty) to fill her position at work during maternity leave. Paula is bright and enthusiastic, and Ellen thinks she’s made the right choice…until she begins to suspect that Paula has a hidden agenda. Can her suspicions be explained away as professional rivalry and her own insecurity of stepping back from her ambitious career, or is something more sinister happening?
