"Cole, founder of New York magazine Trend, is the city's most dazzling playboy. No one knows that five years ago Leora—the girl he loved—fell to her death from the Moonlight Tower of Blackwood Manor in Vermont, leaving him blamed as the heartless man who ""dumped"" her. Behind his cynicism, congenital palpitations strike at night; Leora's oil painting, still his phone wallpaper, is his only guilt.
On Halloween eve, a woman code-named Moon Wolf matches with his friend Jasper on a paranormal app, hinting at full moons, bloodlines, shackles. Then the manor's century-old ""Moonlit Wolf Shadow"" legend returns—flickering lights, midnight howls, a beast in the mirror, a masked figure on the terrace. All think the playboy is crumbling under an ancient curse; only he knows it is a hunt—and he walks into the trap.
