'We really put them through hell'

- 

If you ever have that classic nightmare, where you wake up but then realise with creeping dread that you're still in the dream, and it's getting worse, Until Dawn will either make you feel very seen, or very terrified.

The new horror from Swedish filmmaker David F. Sandberg, of Shazam!, Shazam! Fury of the Gods, and Lights Out fame, is based on the PlayStation Studios' video game of the same name, and sees a group of friends scared witless, stuck in a monstrous time loop.

A year on from the disturbing disappearance of her sister Melanie (Maia Mitchell), Clover, played by 23-year-old New Yorker Ella Rubin, goes looking for her. Taking a gang of mates along for the ride, they suss out an isolated valley where Melanie went missing after sending Clover a final video message. When they come across a deserted visitor centre, they start getting picked off by a masked murder, but then they wake up, and the cycle of death continues for another night... The only way out? To make it to sun-up without dying - but they only have so many chances.
