Kenneth, fixated on ancestor Douglas Weatherford, descends into madness as a fantasy TV show invades his town, disregarding traditions. His obsession with the show's lead actor fuels a tragic downward spiral witnessed by daughter Anna.

Kenneth (Peter Mullan) works in the Arberloch visitor centre as a tour guide, dressing up as the town's most notable historical figure, Sir Douglas Weatherford, an 18th century philosopher and inventor who Kenneth proudly claims as his ancestor. When the village becomes the base of a big-budget fantasy TV show, 'The White Stag of Emberfell', the visitor centre is transformed into an Emberfell fan experience. With the show's costumed fans descending on the town, Kenneth's sanity crumbles as the traditions he holds dear are casually dismissed - a mental decline his daughter Anna (Gayle Rankin) attributes to grief over the loss of his wife. Kenneth's crisis takes an even darker turn when his ire becomes fixated on the show's handsome star, Oscar Sorenson (Jakob Oftebro). The Fall Of Douglas Weatherford is a dark comedy exploring the thin line between history and fantasy.
