In Bruges (2008)

Bruges, the most well-preserved medieval city in the whole of Belgium, is a welcoming destination for travellers from all over the world. But for hit men Ray and Ken, it could be their final destination; a difficult job has resulted in the pair being ordered right before Christmas by their London boss Harry to go and cool their heels in the storybook Flemish city for a couple of weeks.
