While vacationing at a remote cabin, a young girl and her two fathers are taken hostage by four armed strangers who demand that the family make an unthinkable choice to avert the apocalypse. With limited access to the outside world, the family must decide what they believe before all is lost.

Although it's often less than scary and parts of the story don't bear scrutiny, Knock at the Cabin is a thought-provoking chiller and upper-tier Shyamalan.

The plot might be a little underwhelming, but solid acting and plenty of suspense make Knock at the Cabin a decently entertaining watch.
