Seth was an adolescent when he discovered he had a flair for killing; he simply enjoyed it. Killing was exciting, and as he grew older, it gave him a purpose. But the urges stopped the day Rachel moved in next door. She became his best friend; no one was more important to him. Rachel remained his one true friend until the day she died—when the plane her husband was piloting inexplicably crashed, killing most of her family. When a second plane crash takes the life of Rachel’s surviving daughter, Seth’s thirst to kill again awakens. As he searches for the reason behind the tragedies, he begins to discover a grisly truth—one that renews his sense of purpose and prepares him to unleash retribution on everyone involved.
