The Bridge

As the two sides begin to make good progress, host AJ Odudu presents them with a curveball - any team member can put themselves forward to switch beaches. At least one person from each group must move to their rivals, and if no one volunteers, then it's up to the team leaders who goes.

Fractures are starting to show in both camps and the long hours, hard graft and difficult conditions are taking their toll, even on the strongest members of the teams. North Beach decide now is the time for a reconnaissance mission and set out to their rivals' beach in the dead of night.

One of the teams is dealing with a betrayal after one of their own sabotages the build in exchange for some of the prize fund. The team's chances of being first to the money have never seemed so far out of reach. Luckily, there's a lifeline around the corner, as both teams are offered the chance to bid for a carpenter to join their ranks. But they're not bidding in money - they're bidding in the number of team members to go home.

The contestants are in the final few hours of building their bridges. Tensions run high as both teams edge closer to the island and the jackpot - it's neck and neck as they build with fury to be first to finish. Which team will make it to the money first? And who will leave with the jackpot? Presented by AJ Odudu.
