Perry, a successful British design executive, is attempting to create a new design colour, which he calls 'Siam sunset.' His life is unexpectedly turned upside down, however, when his wife is killed in a freak accident that involves a refrigerator falling from an aircraft. Perry subsequently decides to get away for a while and purchases a ticket to go on a bus tour of Australia. He soon meets up with a group of eccentrics, including a woman who has stolen cash from her drug-dealing boyfriend. As the narrative unfolds, it becomes clear, too, that Perry is accident-prone and constantly being drawn into unlikely situations.
