Seeking an escape from a traumatic urban encounter, a young couple, Maya and Jamie, played by Hannah John-Kamen and Douglas Booth, retreat to a quaint inherited cottage in the Irish countryside. Their dream of a peaceful fresh start quickly sours as they face hostility from their aggressively oddball neighbors, the Whelan family, led by patriarch Colm Meaney. Desperate for protection, they heed a local superstition and make an offering to the mysterious, ancient creatures known as the Redcaps who dwell in their garden hedge. Directed by Jon Wright, this folk horror tale descends into a terrifying struggle for survival, where the line between myth and brutal reality blurs. The couple soon discovers that the price for the creatures' help is far steeper and more blood-soaked than they ever imagined, forcing them into a nightmarish pact to defend their home from all unwelcome visitors, both human and otherwise.
