In the 2026 British horror film Jitters, Detective Collymore—a single, divorced father grappling with his own personal demons—is assigned what appears to be a straightforward case: the death of a young woman named Tiffany, initially ruled as natural causes. However, his instinct and dedication push him to look deeper, leading him into the terrifying, supernatural underbelly of a phenomenon known only as 'Jitters.' This malevolent force preys on fear itself, turning the detective's investigation into a desperate fight for survival not just for himself, but for his estranged family.

Directed with a masterful grip on atmospheric dread, Jitters excels in building tension through its bleak UK setting and a compelling central performance. The film cleverly uses the detective procedural framework as a gateway to pure psychological and supernatural horror, making the escalating terror feel earned and deeply personal.
