Kiwi driver Wayne gets a promotion and is sent on a 700km trip hauling a giant 300 tonne excavator to a mine in northern Queensland. The load is so heavy it needs to be shifted in a convoy of four trucks, but an argument between Wayne and lead driver Keith gets the job off to a bad start before they’ve even left the yard. Meanwhile, boss Jon still finds himself with too much work and too few trucks and is forced to dust off THE GOLD-DIGGER, one of his prized show-trucks, to make a delivery. But with no heavy haulage kilometers under its belt in almost 20 years, can it deliver its load problem-free?
