Hosted by Alan Cumming, a shocking murder rocks a tight-knit community to its core. But what if the crime wasn't committed by a stranger or outsider? What if this killer is part of the community itself? Cumming brings us straight into the heart of communities where the unthinkable has happened and no one knows why — or who is responsible. If everyone is a suspect… who can you trust? With multiple suspects, layers of lies, deceit and deception, The Killer Among Us is a murder mystery where someone is playing… but it's not a game.
