Copper City's bloody history is steeped in ghost stories and whispers of serial killers, but three girls have caught the attention of something far more sinister.

A grandmother tormented by visions tried to warn the town, but no one listened. Now, a haunted inheritance has passed to her granddaughters, Audrey and Mara. When Mara's body is discovered in the old mine, Audrey fears her grandmother's premonition is manifesting.

The nightmare begins as Mara's spirit returns—lurking under Audrey's skin, hellbent on vengeance and desperate to rekindle things with her former girlfriend, Zadie. Willing to hijack Audrey's body to get what she wants, Mara drags them both into a deadly pursuit.

When another girl in town goes missing, Audrey, Mara, and Zadie know the killer has struck again. In a fight to solve Mara's death and uncover the mystery of disappearances in Copper City, the girls soon find themselves at war with each other. How do you survive long enough to hunt a murderer on the loose if the person inside you might kill you first?
