Just saw this today. Quite an experience. The film raised many issues about clergy, religion, morality, guilt and forgiveness.
A Catholic priest in NW Ireland is warned during cofession that he is targeted for execution one week hence because of the child abuse sins of other priests. He visits a cast of local characters during that week, each troubled in their personal lives and denigrating of their faith in the church.
Overall a dark film, but thought-provoking (as most dark films are), leavened with wry Irish humour and the bleak (yet beautiful) seascape of the Irish coast.
