시즌 1, 에피소드 4: Sarah Bennett's parents were murdered by a killer known as "The Executioner" 30 years ago. Now, she returns to the quiet community of Waterbury, where the killings occurred, to start over with her husband Dylan, but upon arriving they discover that things haven't changed much. Sarah quickly finds herself at the center of a series of murders that revolve around the seven deadly sins, which appear to be the work of "The Executioner." But the original killer who went by that name, Tom Winston, is in prison so it can't be him. That means somebody else is behind the mask this time around, and the perp's true identity must be discovered to stop this latest string of murders. As long-buried secrets begin to surface, everybody around Sarah is a suspect -- or a victim.
