In the damp embrace of a Portland night, a confession so vile spills from the shadows of the Grotto that Father Thomas flees the confessional. He asks another priest to take over, but fate, it seems, is a fickle deity. The wrong priest ends up with his throat slit, a victim of mistaken identity.

Haunted by his own demons, Detective Johnny Walker takes the case. Battling the insatiable hunger of addiction, he delves into Portland's deceptive heart, unearthing a darkness festering beneath the surface. He’s called upon to navigate the labyrinth of a chilling child serial killer.

As Walker closes in, he walks a razor's edge between justice and his own destructive urges. Can he bring the killer to light before the city, and his own soul, drown in an abyss of depravity? Or will Portland's darkness, a siren song for his wounded soul, claim him forever?
