With the country in the grip of severe drought, the Bush Mechanics are summoned by the rainmaker Jungala to go to Broome in search of rainmaking pearl shells. In the old days, Jungala would have traded bush tobacco for the valuable shells, but now he trades today's commodity - a motorcar he painted with the Rain Dreaming. As Jungala sings them on a safe journey, the Bush Mechanics are beset with dust storms, fires and unfamiliar landscapes as they travel to saltwater country to trade an old Ford V8 for the magical pearl shells.
