Twelve strangers have 17 days to build 330m of bridge to an island, using nothing but their bare hands and basic tools. If they can defy the odds, the teams can claim a $250 000 prize.

The remaining contestants struggle to deal with who they can trust, whether they would steal to win, and how far they would go to take home the prize. However, the loyalties are tested when another twist is revealed.

Day seven arrives and $20,000 is missing from the pot. Trust between the group members reaches an all-time low. Tony and Jessi have to keep their secret to themselves in case the group fails to build the bridge in time.

After two members leave, the group struggle to deal with their decision. Tensions rise with some difficult campfire questions as the team tries to figure out what secrets everyone is hiding.

As the ten remaining builders struggle to finish the bridge, a betrayal happens and the bridge goes up in flames. The remaining builders question whether their goal is too far out of reach.

After Tiana's betrayal, the group of nine must work harder than ever before as they have only two days to complete a quarter of the bridge. With the prize on the line, the builders question who they can trust.
