Reg and Lindsay Morgan own and operate a small Meat and bone meal fertiliser business in country South Australia. While making local deliveries and the occasional roadkill pick up, Reg encounters the crash site of a van, the driver dead inside. Reg recovers the body from the crash and puts it in the back of his own truck. Making his way back to the brothers' plant, Reg is delayed again, this time by three tourists stuck on the side of the road: Sophie, a young woman; James, Sophie's boyfriend; and Wes, James' friend, with whom Sophie is having an affair. Reg takes an instant attraction to Sophie, and, against his better judgement, allows the three to ride with him.
