Hitmen Ray and Ken are sent to Bruges, Belgium, to lay low after a job gone awry in London where Ray accidentally kills a young boy. While Ken finds the medieval city enchanting and is content to sightsee and appreciate the art, architecture, and tranquil canals, Ray is consumed by guilt and restlessness. The younger, more volatile hitman struggles to find meaning in their exile and despises the city, constantly seeking distractions from his inner turmoil. Amidst Ray’s discontent, they encounter various locals and tourists, including a film set with a dwarf actor who debates with Ray about race war theories, and a potential romance for Ray with Chloë, a local drug dealer and production assistant on the film.

The tranquility of their hideaway is disrupted when their boss Harry sends orders for their next assignment, forcing the hitmen to confront their ethics and the consequences of their actions. Harry's traditional code of honor complicates matters as Ken and Ray's relationship and outlook on life are tested. The city of Bruges becomes more than just a picturesque backdrop; it serves as a surreal purgatory where the hitmen must grapple with their past and uncertain future. The looming assignment drives a wedge between Ken's desire to protect Ray and follow his moral compass, and Ray's struggle to find redemption and a reason to live.
