context: The film is set in Arnhem Land, in a time before Western contact, and tells the story of a group of ten men hunting goose eggs. The leader of the group, Minygululu, tells the young Dayindi (Jamie Gulpilil) a story about another young man even further back in time who, like Dayindi, coveted his elder brother's youngest wife. The sequences featuring Dayindi and the hunt are in black and white, while shots set in distant past are in colour. All protagonists speak in indigenous languages of the YolÅu Matha language group, with subtitles. The film is narrated in English by David Gulpilil, although versions of the film without narration, and featuring narration in YolÅu Matha, are also available.
  Minygululu tells a story of the great warrior Ridjimiraril, who suspects a visiting stranger of kidnapping his second wife. In a case of mistaken identity, Ridjimiraril kills a member of a neighbouring tribe. To prevent all-out war, tribal laws dictate that the offending tribe allow the offender to be speared from a distance by the tribe of the slain man. The offender is allowed to be accompanied by a companion, and he takes his younger brother. Whenever one of the two is hit, the spear-throwers will stop, and justice will have been served. Ridjimiraril is hit and mortally wounded but survives long enough to return to his camp, where he is tended to by his eldest wife. After he finally succumbs, the elder brother's kidnapped second wife finds her way back to the camp. She reveals that she had been kidnapped by a different tribe, much farther away and had taken this long to return. She mourns her lost husband, who had attacked the wrong tribe, though now she and the elder wife take his younger brother as their new husband. The younger brother, who was only interested in the youngest of the three wives, now has to care for all of them, and satisfying their many and constant demands is much more than he bargained for.
  Minygululu tells this story in the hope that Dayindi learns of the added responsibilities of a husband and elder statesman in the tribe, and in the end we see Dayindi withdrawing from his pursuit of Minygululu's young wife.
