Repossessing cars to support her small son after being abandoned on the harsh streets of East St. Louis, young single mother Samantha Jones discovers a dying man in the trunk of a car who takes her hostage and forces her to help him reach his protectors.

Helena’s seemingly ordinary life hides a dangerous truth: her estranged father is the infamous Marsh King, the man who kept her and her mother captive in the wilderness for years. When he escapes from prison, Helena is forced to confront her past, and – knowing that he will hunt for her – find the strength to outmaneuver the man who taught her everything she knows about surviving in the wild.
