The Island 2015 kicks off on Channel 4 tonight as Bear Grylls drops off the men at their island.
The series will see a total of 28 people - 14 blokes and 14 ladies - dropped off on two uninhabited islands.
They'll have to survive for six weeks on what the islands have to offer, filming everything that happens themselves.
Both groups must find food, create fire and build shelters, all while avoiding the everyday dangers of jungle life from poisonous plants to torrential downpours from the tropical storm season.
Tonight's show focuses on the men as they start their journey with a splash as Bear chucks them out into the pacific ocean.
With only a day's supply of fresh water and sweltering heat, the first task for the group is to find a place to setup a camp and get a fire going so they can boil clean drinking water.
Building site manager Paul leads the group through the jungle in the search for a clearing, hoping to find a sandy beach on the opposite side of the island.
They get there - just - but with night falling there's no time to make camp or light a fire, so the boys instead spend their first night huddled together on the shore.
The next day the the gang split into two groups, with one battling to start a fire, eventually succeeding with a rather unorthodox method.
But there are rows in the other half as shelter building leads to a clash between Paul and fellow construction industry worker Andy.
After just two days on the Island, BOTH threaten to leave, with Dan declaring: “Everyone just needs to man the f**k up.”
The Island 2015 begins tonight at 9PM on Channel 4.
The show continues tomorrow (Thursday) night with the first episode from the women's island.
