The Sister plot: What’s in store?

The Sister

The past is about to catch up with Nathan...

Russell Tovey plays Nathan, a lost soul who harbours a terrible secret he’s desperate to keep buried. Nathan now has a new life and is devoted to his wife.

However, his world is turned upside down when Bob, a shocking face from the past, turns up on his doorstep. Bob breaks some awful news to Nathan.

This triggers a series of horrific events, which are at the heart of this psychological thriller. Can Nathan ever escape his past? It's a story of "dread, love and possible redemption".

Teasing the drama, Russell tells us: “At a New Year’s Eve party 10 years ago Nathan fancies this girl but they go for a drive with Bob and something happens and the girl dies.

"Nathan has rebuilt himself and put Pandora in the box, but now Pandora’s running around crazy and he’s trying to get her back in. He’s riddled with fear. It’s about the unravelling of a good person who got involved in a situation he shouldn’t have.”
