Seven millenials discover an obscure electronic board game and decide to test their wits against it. Positioning their fingers on respective buttons, they each receive a pinprick and a few drops of their blood trickles towards the centre of the board. An on-screen message flashes that now a grand total of 24 people must be killed as quickly as possible or one of them will be randomly eliminated via head explosion. It's kill or be killed as they either turn on each other or start searching out innocent victims.
