Forty-year-old couple Andrew and Eric and their adopted seven-year-old daughter Wen leave their home in Cambridge, Massachusetts behind to spend a vacation in a secluded cabin in New Hampshire.

They foresee an upcoming apocalypse in which Leonard claims the oceans will rise, there will be plague, the sky will fall, and finally an unending darkness will descend.

When the family refuses to choose, the visitors conduct a strange ritual in which they cover Redmond's head with a cloth mask and beat him to death with their weapons.

Eric has begun to wonder if the story is true and has visions of flies that lead him to turn on the TV, which shows an outbreak of bird flu.

Sabrina describes how she and the other visitors were led by their visions and compulsions to find each other online, execute details of their plan such as creating their weapons, and to continue forward when they wanted to resist.

The TV shows seven spontaneous plane crashes taking place around the world, seemingly fulfilling the prediction of the sky falling.

Eric considers taking his own life, but Andrew argues that even if the apocalypse is real, he refuses to obey a god that does not accept Wen's death as enough.

It was written, directed, and produced by M. Night Shyamalan, and stars Dave Bautista,[6] Jonathan Groff, Ben Aldridge,[7] Nikki Amuka-Bird, and Rupert Grint.
