Twelve strangers, including Trisha Goddard's daughter and a plumber, face an epic challenge: to build an 850-foot bridge in 20 days, to reach an island where a £100,000 prize awaits.

The £100k reality challenge continues. Luke and Maura return to camp with a secret. Zac's leadership is in doubt as the team fall behind schedule. Two arrivals face a terrible choice.

Newcomers Ross and Susie must evict a teammate. As hunger and fatigue take hold, tempers fray. A flare brings the promise of a luxury banquet - but at what cost?

With less than half of the bridge built, emotions run high and rumours are rife. One teammate wants to leave, but will they go home empty-handed?

The group are shocked by former teammate Luke's actions. With the odds stacked against them, can they pull together, finish the bridge and claim their prize?
