The film delves deeper into the realm of fear, thrills and cruelty. “Oh, the horror!” is probably what a group of smartphone-addicted teenagers think when they are sent to an “offline camp”. Instead of browsing and scrolling, they walk around the woods and chat – using their tongues rather than their thumbs. Soon, dread and terror rear their ugly heads when the group is faced with a killer who starts picking them off one by one.
