Sanna, her big sister Oksana and her friend Robin are driving along deserted country roads on their way to Mum’s house to celebrate Halloween. Suddenly something in the car starts beeping and they have to stop for the night. They check into a hotel where they are the only guests. In the evening, the boy on reception goes home for the night. They are all alone an old hotel. Or are they really all alone?

Suddenly Oksana vanishes and the hotel starts to change. Or is it just Sanna and Robin’s imagination? They hear footsteps, the walls seem to start moving, and a mysterious grey girl appears and asks them for help. Then they find Oksana – but she’s in one of the many class pictures on the wall. Something is wrong. Terribly wrong!

Sanna, who loves horror films, realises that they’ve ended up in a scary movie – and they won’t be able to escape until they find out what the hotel wants from them. It may help to know every horror movie trick and tip in the book – but that doesn’t make it any less scary to be trapped in a living, crazy and super-scary hotel with a bunch of schoolkids from the days of the Second World War.
