After committing a brutal crime, a group of four friends think they have hidden the truth forever, but the discovery of a vintage board game threatens to expose their horrific secret. With one move, they summon the vengeful demon 'Grin' who targets those who have committed the most terrible sins. The group scrambles to find a way to break the curse, before the demon claims them all in this nightmarish game of horror and retribution.
'Grin' stars Gareth Tidball ('Rob1n & Havoc'), Samuel Lane ('Right Honourable Gentlemen'), Ellen Jane-Thomas ('Bohemian Rhapsody') and Luke Rhodri ('Doctor Who').
