Deep in Tasmania's untamed wilderness... 12 strangers meet in their quest to build a bridge. But how will the $250,000 cash prize tempt them and as they get closer... how will the bridge change them forever?

Would you steal from your friends? Would you lie for money? Who can you trust on the Bridge?

It's day seven, $20,000 has been stolen from the prize money and trust within the group is starting to splinter. But The Beacon taunts Tony and Jessi, who must keep their secret under wraps lest the group fail to build The Bridge in time.

With two members voted out, the group struggles with their decision, and tensions are brought to a head with some tough campfire questions.

As the ten remaining builders struggle to finish the bridge, a betrayal happens and the bridge... goes up in flames. Who was it? Why did they do it? Where was the opportunity for sabotaging the bridge?

After an act of betrayal from Tiana the group of nine have just 2 days to complete a quarter of the bridge. They must work harder than ever before but the reality of the $200,000 getting ever closer means that end game plans are being made.
