Ryan Cloverhill, founder and CEO of the world’s most popular social media platform, invites his six best friends from college to his home on his private island near Puget Sound. For Stephen, Emma, Perry, Will, Beau, and Lainie, day one is just what the doctor ordered. Day Two, however, takes a bewildering turn when the six hungover guests wake up to find that their host has disappeared, along with all connection to the mainland. A touchscreen tablet of unknown make awaits them, blatantly defying the rules of the weekend with its on-screen challenge: Unlock Me! The passcode to the tablet is hidden somewhere in the group’s shared history. Only one thing is clear: their old friend Ryan has something unthinkable planned. Now it’s up to the six of them to stop him. And when this weekend is over, the world will never be the same.
