1969年2月的某一夜一架噴射機在澳洲鄉野小鎮外圍的平原上盤旋不去，12歲的約翰?安德生，綽號野狗，因為他自任自己的叫聲像野狗一樣，和一群鄉土小民一起蜂湧而至，彷若來的是飛碟一樣。在這裡，野狗聽見一隻爵士樂團正在演奏，美妙得叫他一輩子也難以忘懷，第二天他醒來，樂團和噴射機皆化為塵土彷若一場科幻的夢一樣。轉眼20年過去了。他結了婚有了小孩了，他想這輩子就要完蛋了，他不甘心，於是他緊追自己最後一絲夢幻，他買了機票到達巴黎。他開始漫無目標的在各大城市找尋比利?克羅思和他的樂團。但60年代早已飛逝了，他也有多年未曾公眾演奏了，整個世界早已進入另一個新的星球裡。野狗再也難以辨認他了，但有一天他進入吧裡，聽見了小喇叭的聲音，是的，聲音又開始召換他了。這時他的幻夢不再只是童稚的癡人囈語。於是他動身……《澳洲爵士春秋》終於圓了導演多年的夢，因為飾演比利的正是爵士大王邁爾斯·戴維斯（Miles Davis），這是他接近死亡之前的天鵝之歌。

Steve is a man who has it all, a successful career, wonderful children, beautiful home and a loving wife. However, returning to his home after work on his birthday, he finds his house deserted and darkened with almost all the lightbulbs missing, all easy access outside cut off and a videotape waiting for him. Playing that tape, he watches a bizarre and grueling recording in which his wife explains her grievance with him, her reasons for disappearing with the children and her revenge for how he treated her in a way he would never forget.
