In 1968 Australia, three small-town Aboriginal sisters (Deborah Mailman, Jessica Mauboy, Miranda Tapsell) sought identity and success through their gift for harmony. With the tutelage of a hard-partying Irish session man (Chris O'Dowd) and the recruitment of a fourth in their mixed-race cousin (Shari Sebbens), they get their first real break as they're sent to Vietnam to entertain U.S. troops. Fact-based crowd-pleaser co-stars Tory Kittles, Eka Darville. 99 min. Widescreen (Enhanced); Soundtracks: English Dolby Digital 5.1, French; Subtitles: English (SDH), Spanish; featurettes; interview.
