(In best terrible attempt at an Irish accent) It's fucking brilliant is that!
Two hitmen have to spend some time in Bruges, Belgium. Colin Farrell's Ray, really doesn't want to be there, isn't enjoying himself and thinks it's a "shithole". Brendan Gleeson's Ken, actually quite likes it, enjoys the architecture and takes the time to sightsee.
It's a fair bit more involved than that, but that's your basic character premise there. It's offensive to the point where we wondered exactly how they got away with it, it's also bloody funny, touching, brilliantly written and outstandingly acted.
