Exam

The film is set in an alternate history, present-time United Kingdom. Eight candidates dress for what appears to be an employment assessment exam, entering a room and sitting at individual desks. Each desk contains a question paper with the word "candidate", followed by a number, from one to eight. The Invigilator, a representative of the company named DATAPREV, explains that the exam is 80 minutes and consists of only one question, but there are three rules. The candidates must not: talk to the Invigilator or the armed guard at the door, spoil their paper, or leave the room. If they do, they will be disqualified. He asks them if they have any questions, and then leaves the room.
