New York musician Jude Rossi's world is shattered when his 14-year-old daughter, Little Blue—a rising star in the music scene—dies unexpectedly at her record deal party. Though the coroner’s report lists “overdose,” Jude knows that his daughter’s disdain for drugs means there’s something far more sinister at play.

With no means to investigate, he spirals into a dark abyss of grief, turning his back on his once-thriving music career. Two years later, Jude works as a low-paid janitor in a boxing gym. One fateful night he encounters Mad Madge, a homeless woman claiming she can reconnect him with his daughter. Desperate and intoxicated, he consumes a strange serum and is thrust into a nightmarish realm. There, Little Blue’s spirit reveals that a snake-tattooed man is responsible for her death, igniting a fierce hunger for vengeance when Jude awakens in a hospital bed.

As Jude spirals deeper into his obsession, he meets Lauren Banks, an addiction psychology student who distracts him from his deadly vendetta. With her help, he begins to reclaim the life he lost, even landing a job at her father's entertainment law firm. But the haunting messages from spirits pull him back into the darkness, unraveling a web of truths about music industry execs and his daughter’s tragic end. Nothing will stop Jude from seeking revenge for his little girl. However, he is unprepared for the lengths some will go to protect their secrets and power.
