It’s one thing to find out someone in your family doesn’t like your favorite show or is obsessed with Benedict Cumberbatch. It’s something else entirely to find out they’re, say, a murderer. And that’s the dilemma facing the family at the center of American Gothic .

EW has an exclusive first look at the first promo for the new CBS show, which stars Virginia Madsen, Anthony Starr, Juliet Rylance, and more as it tells the story of a Boston family that realizes someone in their family could be linked to an infamous string of murders. Over the season’s 13 episodes, the suspicion that a killer is in their midst threatens to tear the family apart.
