Dougal Brett is one unusual truckie, he flies his own helicopter, owns a cattle station the size of a small country and a fleet of live stock trucks. Heavy haulage driver, Mark King is half way through a marathon job. He's in charge of getting a monster mining truck from Brisbane to the central Queensland. On a lonely dirt road at the top of North Western Australia, veteran Perth's truckie, Steve Grahame, is a broken man. 50 kilometres short of his destination. Part of a dirt track has collapsed under the weight of his 100 tonne road train.
