Sandy Edwards (Toni Collette), an ambitious geologist, suddenly finds herself having to baby-sit Hiromitsu (Gotaro Tsunashima), a habitually silent Japanese businessman. Hoping to strike up a business deal, she agrees to take him on a field trip around Western Australia's remote Pilbara desert. Against the background of the outback, these two diametrically opposed strangers find themselves thrust together in a potentially life-or-death situation. As they journey further into the desert, they leave more of what they know about each other and themselves behind. The film oscillates between a cross-cultural journey, an emotional drama, and a haunting love story, while director Sue Brooks catches her audience off guard as she takes us down an unexpected route.
