The three sisters, Mia, Maisy, and Bronte, are hesitant to leave their home behind and venture out into the wilderness with their Aunt Caroline. Caroline is insistent, however, that they need to leave before the pandemic fully takes hold and they are all stuck inside their house.
As they settle into their campsite, strange occurrences begin to happen: Tents are moved, food is missing, and shadowy figures can be seen just beyond the tree line. The girls initially brush it off, thinking it's just their nerves getting the best of them.
But when they stumble upon a makeshift campsite that seems to belong to someone else, they realize they may have unwittingly led their stalker right to them. As the days wear on, tensions rise and they become increasingly paranoid, unsure of who to trust.
Meanwhile, the pandemic is still raging, and they worry about the safety of their loved ones back home. With limited resources and no easy way to call for help, the girls and their aunt are forced to fend for themselves and face the terrifying presence that has been stalking them.
In the end, it becomes a fight for survival as they navigate the treacherous woods and try to outsmart their stalker. Will they make it out alive, or will they become victims of the wild and dangerous backcountry?
