In a gripping thriller, the story revolves around the retiring detective Jerry Black, portrayed by Jack Nicholson. Just as Jerry prepares to bid farewell to his decades-long career at his retirement party, an unexpected case strikes—a horrific rape and murder of a young girl that has recently come to light. As the local police seem all too eager to wash their hands of the matter, it falls upon Jerry to deliver the devastating news to the girl's heartbroken parents. In a moment charge with emotion, the devastated mother extracts a solemn promise from Jerry, imploring him to find her daughter's killer for "upon his soul's salvation."
Intriguingly, authorities quickly arrest a developmentally challenged Native American trapper, who was spotted near the crime scene and has a troubled history involving previous offenses. However, the investigating officer resorts to dubious methods to wring a confession from this vulnerable man, who, in a wave of confusion and guilt, culminates in taking his own life. Though this case seems closed, Jerry feels a lingering obligation to dig deeper.
With unwavering determination, Jerry delves into the investigation and speaks with the victim's closest friend. This friend reveals a mysterious acquaintance referred to as "The Giant" or "The Wizard," who had been seen doling out small porcupines to the girl. Following this lead, Jerry discovers a drawing the victim made—an innocent reminiscence of herself alongside this Giant. This clue enriches Jerry's growing portfolio as he uncovers two other unsolved cases bearing eerie similarities to this tragedy. One of these murders occurred during the time the arrested Native American was in custody. Despite being officially retired, Jerry feels compelled to keep his vow and pursue the truth behind the sinister events.
In pursuit of answers, he acquires a store and gas station in the vicinity where the calamities transpired. It's here that he meets Lori, a local waitress-bartender played by Robin Wright Penn. Lori has a young daughter who unfortunately fits the grim profile of the previous victims. Equally tragic, Lori is a survivor of domestic abuse, and one stormy night, after a brutally violent encounter with her husband, she seeks solace from Jerry. He offers her and her daughter a temporary refuge, assuring her there are "no strings attached," but in time, this arrangement evolves into something deeper as they find themselves living together.
As the narrative escalates, interspersed scenes offer glimpses of potential suspects and lead Jerry further into a web of secrets. Eventually, it is revealed that the little girl casually mentions a man named "The Wizard," who has invited her to meet him at the local picnic grounds the next day. She shows Jerry chocolate porcupines, gifts shared by this enigmatic figure, igniting his suspicions yet again.
Determined to catch the elusive perpetrator, Jerry arranges for a stakeout at the picnic grounds with some of his former colleagues. However, their patience wanes, and the officers abandon their posts, intending to inform Lori of the unsettling situation. In a tension-filled moment, Lori confronts Jerry, hurling accusations that leave him bewildered before hastily taking her daughter away.
As they drive back, tragedy strikes once more when the officers stumble upon a blazing vehicle, and inside is a dead driver. Suspended from the rear view mirror is a tiny chocolate porcupine, a chilling reminder of the sinister ties connecting these events. The film culminates with Jerry, now desolate, seated in front of his seemingly abandoned gas station, drowning his sorrows in a bottle and muttering to himself, as the haunting mystery lingers on.
