When a joint British/U.S. military operation remotely isolates a known terrorist cell in a Nairobi neighborhood, commanding officer Col. Katherine Powell (Helen Mirren) is poised to give American drone pilot Steve Watts (Aaron Paul) the kill order. As a young girl wanders into the line of fire, however, all involved find themselves in a tense battle of wills and ethical challenge. Gavin Hood’s sobering exploration of modern warfare’s morality co-stars Lex King, Jeremy Northam, Michael O’Keefe, and, in his final screen performance, Alan Rickman. 103 min. Widescreen (Enhanced); Soundtrack: English Dolby Digital 5.1; Subtitles: English (SDH), Spanish; featurette.
