Na cloigne (2010)

Sean has a flaming row with his wife Nuala when he comes home from the pub one night--with a couple of good-looking women. Nuala goes off in the car, leaving Sean at home. When he wakes up the next morning, he finds himself covered in blood with no idea what happened the night before. Even as a murder investigation goes on around him in the following days, Sean has no clear understanding of the events of that night and of who is dead.
