To those around her, Sandy is the archetypal Australian woman - bold, brash, confident and up to any challenge. But when she is charged with playing tour guide to a Japanese businessman who is a potential investor in her company, it is not a task she relishes.
Driving across the vast Australian outback, cultural and personal differences make for an uncomfortable ride. Hiromitsu's uncommunicative manner and sexist comments irritate Sandy, but she must keep her feelings to herself if she is to prevent offending her company's guest. For Hiromitsu, Sandy is everything that he finds unappealing about western women - she is loud, aggressive and headstrong. However, they soon find they are attracted to each other, and an unusual and intense relationship develops.
Beautifully observed, emotionally-charged and full of unforeseen surprises, this unique film features a blistering performance from Toni Collette (Muriel's Wedding, The Sixth Sense, The Hours) and was a huge international box office and critical success.
