Not just the trailer, the whole film is set on a computer screen.
Unfriended tells the story of a group of teenagers who are contacted over the Internet by an unknown party. One year prior to the film's event, a teenage girl committed suicide when a video was anonymously posted to the Internet, showing her in a drunken state.
The film shows the teenagers being offed in increasingly creative ways, all by the unseen party who wants to know which of them posted the video. At the very least, you've got to hand it to the makers for being inventive.
Here's the first trailer.
