Sally Bretton (of Beyond Paradise and Not Going Out fame) leads the cast as Zoe Dalton, a business professional who moves into a beautiful home next door to her father (played by Agatha Christie's Poirot star David Suchet).

Things quickly take a turn for the worse, when the au pair hired to help with caring for Zoe's two children begins enacting a scheme of her own with terrifying consequences.

The full synopsis, courtesy of Channel 5, reads: "Zoe Dalton is a woman who seems to have it all: a successful business, a happy marriage, two beautiful step-children and a stunning house in the idyllic countryside.

"When a mysterious au pair enters Zoe's home with her own hidden agenda, Zoe is unwittingly propelled on a journey that will unearth a terrible truth and which will threaten to destroy everything she holds dear."

Suchet has been absent from our TV screens for several years, with his last gig being a voice role in the first season of His Dark Materials and a live-action appearance in Mike Bartlett drama Press.

On the absence, he told Radio Times magazine: "The Au Pair was the first thing I had to do [since then], it was a real page-turner. Other roles I was offered were nice, but repetitious and not quite challenging enough."

The Au Pair premieres on Channel 5 on Monday 10th March 2025. Check out more of our Drama coverage or visit our TV Guide and Streaming Guide to find out what's on.
