Across the globe, five strangers receive a horrifying message from an unknown number.

THE PERSON YOU LOVE MOST IS IN DANGER.

To save them, each must play The Game – a sinister unknown entity that has a single rule: there can only be one winner.

IF YOU LOSE, YOUR LOVED ONE WILL DIE.

But what is The Game – and why have they been chosen?

There’s only one thing each of them knows for sure: they’ll do anything to win…

WELCOME TO THE GAME. YOU’VE JUST STARTED PLAYING.
