A global plague and world war created them-monsters in human skin.

Shane contracted the mutation during the third World War, a corruption of the blood that forces him to violently shift into an animal every month. He uses his heightened senses to track down the missing or murdering dredges of humanity. His only safe haven is a hustler with the ability to see other people's pasts.

A psi, hiding in plain sight, Misaki spends his days pleasing men for money and basking in beautiful shoes. Shane's presence in his life sometimes means gruesome murder cases and memories that give him nightmares, but he can't help being drawn to the gruff detective.

When an official's daughter goes missing, Shane asks for Misaki's help. But the trip into the killer's mind opens a door to evil long forgotten and it's coming for them next.
