Synopsis
When Eva returns home to visit her family, everything seems normal until her mother’s new partner Lucian discovers an old vintage board game hidden away for decades, which quickly becomes something far more dangerous when the game’s disturbing rules are followed and a supernatural force is awakened.
The family soon discovers they have unleashed Grin - a grotesque, smiling demonic clown that does not simply kill its victims, but hunts those carrying hidden guilt and unresolved crimes, and as members of the family begin disappearing one by one, Eva must uncover the truth behind the game and confront the buried secrets within her own family before the curse consumes them all.

About Grin
Grin is a 2026 British supernatural horror film from director Lawrence Fowler, expanding the filmmaker’s Jack in the Box horror universe while shifting the focus from haunted toys to cursed objects and supernatural folklore.
Produced by Fowler Media, the film combines slow-burn supernatural horror with creature-feature elements, using practical effects, unsettling atmosphere, and psychological terror to explore themes of family trauma, guilt, and karmic punishment.
The film also continues Lawrence Fowler’s interest in bringing classic horror ideas into modern supernatural stories, blending eerie mythology with traditional scares, creature design, and escalating tension, and with an estimated budget of around $2 million, the production aims to deliver a darker, more ambitious entry into Fowler’s growing horror universe.
