Starting from Alice Springs, the eight truckers' ultimate Australian challenge is to haul four huge, prefabricated buildings for a medical center across 500 miles of hostile desert to the remote Aborigine community of Kiwirrkurra. Driving with the same partner as the previous challenge, at the end of this three day journey, the weakest team will leave the competition.
After the Australian eliminations, the six remaining truckers take on the infamous BR163 road through Brazil's wild and unruly cattle lands. Their cargo is 11 x half ton concrete pipes. This load is oversized, fragile and near impossible to secure — as they soon discover. In new driver pairings for the first time, their 3 day 360 mile journey becomes a battle between speed and strategy with surprising results.
It's half way through the competition and this job is the game changer. Six truckers travel deeper into the Amazon to deliver fishing boats to a fishing community along brutal and unforgiving, dirt tracks, fueled by adrenaline and competitive spirit two of the teams race aggressively through the jungle for a winning time. Meanwhile, the third team take a steadier approach. Which strategy will deliver the best results?
