Plumber Luke and hotel entertainer Maura return from their overnight mission with a huge secret that could jeopardise the bridge build. As bad weather and dubious construction methods hamper the team's progress, Zac's leadership is called into question. With the team way behind schedule, two new arrivals make a surprise entry into the camp.

The team wakes up to the realisation that more than half of the bridge still needs building - and that they will likely lose a team member too. With rumours spreading through the camp that a splinter group are plotting to vote someone out, it soon transpires that the whispers are part of an intricately calculated game plan to crown a new leader.
