In the outback town of Cummeraganja in the mid-1960s, aboriginal sisters Gail, DEBORAH MAILMAN, and Cynthia, MIRANDA TAPSELL, enter a talent contest at the local pub; their parents won't let their younger sister, Julie, JESSICA MAUBOY, enter because they think she's too young - but she comes anyway and though the disdainfully racist judges don't award them a prize, the trio catch the eye of laid-back, alcoholic Irish MC Dave, CHRIS O'DOWD, who senses talent if only they will sing soul instead of country and western. When they see an ad wanting entertainers for the troops in Vietnam, the girls and Dave sense an opportunity - and soon, joined by their cousin Kay, SHARI STEBBENS, a victim of the Stolen Generation who's been living in Melbourne, they're off to the war zone.
