In the remote woods of Oklahoma, Bowdrie, a rugged loner with a shadowy past, lives a quiet, disciplined life with his daughter, Tag - a sharp, independent girl who was raised off the grid. Their simple existence is disrupted when Tag stumbles upon a badly injured woman near the river while out fishing. The woman, January, is bloodied, beaten, and near death. Despite Bowdrie's instincts to remain distant, he and Tag take her in and tend to her wounds. As January slowly recovers in their cabin, the truth begins to emerge. She and her best friend Lizzie were kidnapped by masked men linked to a violent criminal named Alejandro. The women were tortured for information about a man named Jensen, a former associate of the gang. January survived being shot and dumped in the river-Lizzie did not. Bowdrie confirms this grim reality when he finds Lizzie's body tangled in river debris, bearing a bullet hole in her forehead. Tensions rise as Bowdrie debates the danger of keeping January hidden. His primary concern is protecting Tag, who is growing attached to January. Meanwhile, Alejandro, ruthless and unstable, continues hunting for Jensen-and anyone connected to him. He abducts Jensen and his wife, signaling the violent reach of his operation. The story builds toward a quiet but intense moral reckoning. Bowdrie decides to take January into town, knowing that doing so may expose them all to Alejandro's wrath. As the father-daughter bond between Bowdrie and Tag is tested by hard truths and looming threats, MERMAID explores themes of survival, redemption, found family, and the human cost of violence. The ending leaves the audience in quiet suspense, as safety remains uncertain and choices weigh heavily.
