Twelve strangers come together in the British countryside and embark on a 20-day challenge in the hopes of winning a £100,000 prize. The participants must work together to build an 850ft bridge to an island in the middle of the lake where the prize is being held, but there will be a series of problems along the way, which will test their teamwork, skills and determination. The participants are from a wide variety of backgrounds, including a teacher, a plumber, and a dancer, and all have something different to bring to the challenge.
