In the heart of Northern Michigan's untamed wilderness, young Helena (Brooklynn Prince) lives with her parents, Jacob Holbrook (Ben Mendelsohn) and Beth (Caren Pistorius), in a quaint cabin that serves as their modest home. Their peaceful existence is disrupted when Beth urgently calls Helena back to the cabin, but the spirited girl is distracted by tracking deer with Jacob. In her eagerness to impress her father, she takes a shot at a deer but misses, leaving Jacob disappointed. To uplift her spirits, he marks her forearm with a tattoo, symbolizing a reward for her determination.
As time passes in the woods, Helena and Jacob’s relationship deepens through their shared adventures. However, their bond faces a harsh reality when they discover the remains of an animal that had resorted to gnawing off its own limb in a desperate escape. In stark contrast to their growing connection, Beth becomes increasingly anxious about their isolated lifestyle, beseeching Jacob to make a change, only to be met with his unwavering indifference.
Just when their secluded life seems stable, an unexpected visitor arrives on an ATV, setting off a chain reaction that will irrevocably alter Helena's life. The stranger appears at their door, lost and in need of help, but Beth urgently urges him to leave, which provokes Jacob’s violent outburst. This fateful encounter leaves profound consequences, forcing Helena into a moral conflict between her loyalty to her family and her innate sense of right and wrong.
As years go by, the repercussions of that day manifest, and an adult Helena (Daisy Ridley) has transitioned into suburban life, camouflaging her facial tattoos under layers of makeup while navigating a world far removed from her upbringing. Her life is filled with the mundane rhythm of a desk job, enriched occasionally by tender moments with her daughter Marigold (Joey Carson) and husband Stephen (Garrett Hedlund). However, the past resurfaces when Special Agent Illing (Yanna McIntosh) confronts her, compelling Helena to face long-buried secrets.
As Jacob's shadow looms over her new life, Helena's facade begins to crumble. Stephen discovers the truth about her tumultuous history, putting their relationship under strain as they grapple with the reality of her past. Amidst this turmoil, Helena is challenged to confront the very demons that have haunted her existence, all while maneuvering through a perilous landscape where the boundaries between fact and deceit constantly blur.
During a news broadcast, a chilling realization grips Helena – her very existence is tied to Beth’s abduction and tragic demise, a horrifying event that has shaped her family’s legacy. Meanwhile, Stephen takes Marigold to a hotel, leaving Helena to wrestle with her thoughts alone. She retreats to her childhood haven, a place filled with hidden mementos, including a weathered hunting knife and beloved wand. As she immerses herself in the isolation of the forest lake, Jacob and his accomplice plot their return, the threat of their sinister plans looming like a ticking time bomb.
A visit from Sheriff Clark (Gil Birmingham) delivers a somber reminder that Beth never had the chance to meet Marigold, highlighting the tangled threads of their family dynamics. Helena opens up to Clark about her profound fears, confessing how Jacob's presence tainted Beth’s love for her, as if he had darkened a piece of her heart. Clark reassures her that Stephen will understand and forgive her when he learns the truth.
News breaks that Jacob’s body has been discovered in a burned vehicle near the Canadian border, sending shockwaves through Helena's world. As she grapples with the reality of this revelation, she hesitates to tell Stephen, wary of his reaction and what it could mean for her identity. The specter of Jacob's malevolence keeps looming large, casting a dark shadow over their lives.
As days turn into an overwhelming blur, Helena's psyche starts to erode. Hoping for solace, she brings Stephen and Marigold to Sheriff Clark, yearning to share the nostalgic tales of her past. Yet Clark is a stern reminder that Jacob's malice stemmed from his own darkness, devoid of any redeeming qualities. Stricken from a nightmare, Helena fears Jacob has breached their home, only to find her fears unfounded, traced instead to Marigold’s innocent playfulness.
Her paranoia escalates at the farmers market when she mistakenly identifies a stranger as Jacob, becoming obsessed with his every movement. The illusion fades as quickly as it formed, leaving her unsettled. Back home, she sets up an array of defenses around their property, her anxiety peaking.
Tucking Marigold into bed, Helena reminisces about the straw doll Beth once gave her – a symbol of hope undimmed by despair. But tranquility is shattered by the ringing phone, with Sheriff Clark urging her to overcome the darkness that has haunted their family for too long. Yet, as she stares at the scattered straw dolls in Marigold’s room, a chilling thought creeps in – Jacob’s vile spirit may still linger, poised to threaten once more.
In the wilderness, Helena’s words linger like a silent oath as she embarks on a painful journey back to her childhood cabin, holding vast memories. Instead of finding peace, she confronts a shocking reunion – Jacob, the man who once controlled her fate. His return ignites a tempest of emotions, with him longing to rebuild their fractured family and resurrect the life they pursued in nature. However, Helena’s journey has led her to a new realm of belonging, firmly closing the chapter of her past that he represents.
As tensions flare, she stands her ground against Jacob's disillusioned pleas. Memories of violence, Beth's tragic disappearance, and the web of lies that ensnared her come crashing to the fore. Just as emotions reach a peak, Helena finds herself face-to-face with Sheriff Clark, who had silently followed her. Before she can articulate her pain, Jacob's brutality re-emerges, leading to Clark’s tragic end and leaving Helena trapped and alone, a pit of memories around her.
But Helena is unyielding. Drawing from the survival lessons Jacob once imparted, she orchestrates her escape, determined to hunt him down through the woodlands. As their final confrontation unfolds, Jacob faces not just a fierce opponent, but a woman who has embraced her truth, no longer shackled by his manipulation.
In a harrowing confrontation, Helena and Jacob tumble down a cliff into the rushing river below. As they struggle to breathe, she claims a gun, silencing Jacob’s reign of terror once and for all. Empowered by resolution and driven to shield her family from those capable of harm, she releases Jacob’s lifeless form to the current, kayaking back to the safety of civilization. This pivotal moment marks not just the conclusion of one chapter in Helena's life, but the hopeful emergence of a new beginning.
