From NetFlix:

Colin Farrell stars in this psychological drama about a photojournalist who returns home from a harrowing news assignment without the colleague who’d accompanied him. Now, his girlfriend (Paz Vega) will not rest until she finds out what took place. Bosnian helmer Danis Tanovic, whose No Man’s Land won the 2002 Academy Award for Best Foreign-Language Film, directed this taut, dark drama shot on location in Ireland

Colin Farrell does an acceptable job portraying a grief-striken man in a state of denial. The war scenes in Kurdistan are grim. The title is perfect and refers in part to the beginning of the film in which a Kurdish battlefield doctor with almost no equipment routinely shoots all wounded men in horrible pain for whom he can do nothing. You must wait until the end of the film to learn why Colin Farrell is in such psychological pain.

Important topic but a somewhat mediocre film.
