Seven years ago, Riley Kingston survived a camping trip in the Montana mountains that took the lives of her friends and left Riley certain something followed her out of the wilderness. After years of untreated PTSD and unanswered questions, Riley returns to her family's remote ranch determined to finally put the past behind her.

Instead, she senses the presence in the mountains never left, and may be growing stronger.

When dead cattle are discovered on the property, sheriff's deputy Jake Hansen investigates. The crime mirrors a disappearance from his own past, one that was never solved and quietly dismissed as an accident.

As Riley and Jake begin to compare notes, they uncover a connection between the cattle, the disappearance of a snowmobiler, and an old regional legend of the Blackfeet Nation. The entity stalking the ranch has been feeding for generations, preying on isolation, fear, and unresolved trauma.

As the attacks escalate and the boundaries between psychological and supernatural horror blur, Riley must confront what truly happened during the camping trip and decide whether she is haunted by a manifestation of trauma or an ancient force that demands a reckoning.

If she's wrong, she won't survive a second encounter.
