Knock at the Cabinfollows a gay couple - Andrew (Jonathan Groff) and Eric (Ben Aldridge) - and their daughter as they are taken captive by four armed strangers while vacationing in a cabin in the woods.
The new trailer also gives us full plot details of the movie for the first time. While we'd known that the family in the cabin had been chosen for a globally important mission, we didn't know exactly what it was. Now we do.
The family has been trapped inside their cabin by four captors played by Dave Bautista, Rupert Grint, Abby Quinn, and Nikki Amuka-Bird, and are told that they must make a decision if they want to save the world.
"Families throughout history have been chosen to make this decision," an intimidating character played by Dave Bautista calmly explains to the captive family. "Your family must choose to willingly sacrifice one of the three of you to prevent the apocalypse."
The movie appears to be an edge-of-your-seat thriller and an instant Shyamalan classic in the line of The Sixth Sense and Signs. But it also looks like a truly great gay family drama. "There is nothing more flawed and perfect in this world than our family," Groff's character says.
There's also some pretty terrifying footage of giant tsunami waves crashing into a beach. "For every 'no' that you give us, hundreds of thousands of people will die," Bautista's character tells them.
We don't know if there will be a classic Shyamalan twist, but one big twist that happens in the trailer appears to be Groff's character "seeing something in the light" that changes his view on the situation. It seems there's more to this cabin than we first thought.
Knock at the Cabin opens February 3 only in theaters.
