Gabriel is a former undercover cop haunted by the things he's seen and done. He returns to his small hometown of Prophet, taking on the role of sheriff, hoping to mend his fractured relationship with his estranged brother and rebuild his life. But when a chilling murder occurs at Sentinel Rocks, a sacred Makah site on Lake Prophet, Gabriel's dreams of peace and reconciliation are shattered.

Gabriel navigates a web of intrigue, where suspects abound; from local tribal elders to fervent Solstice worshippers and even those hunting the elusive Big Foot. When the brutal murder leaves Duke, a loyal Labrador retriever, as the sole witness, Gabriel stumbles upon an unexpected ally—a local animal behaviorist named Tiber.

Tiber, a newcomer to Prophet, seeks refuge in this remote haven. Armed with his extraordinary ability to communicate with animals, he offers his expertise through video consultations. While he attributes his skill to his academic background, his intuition and flashes of insight owe as much to his Navajo heritage as to science.

With the relentless rain washing away sins and good intentions alike, Gabriel and Tiber must begin to confront their vulnerabilities and unravel the truth.
