Documentary following the adventures of two brothers, 11-year-old Felix and 10-year-old Luca, who live on an island called Fofoa in Tonga. After living through the worst tropical cyclone in memory, Felix and Luca enlist a local conservation charity to help them survey their coral reef to see the effects of the storm and check the long-term damage from climate change. Protecting the marine life is vital to keep attracting the migrating whales back every year, not least because the boys' favourite hobby is taking visitors swimming to meet these magnificent animals. Join Felix and Luca as they show you what living on an island is all about.
