The Bridge 1-3

The Betrayal. 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?

Twelve strangers are tasked with building a 330-metre bridge, in only 17 days. In the end only one person will be able to cross the bridge to collect the prize.

Double blow. The expedition team return with extra rope but the reward comes with a price. Also in an unexpected twist one of the expedition team has to be sent home.
