Sixteen contestants are stranded on a remote island and must battle it out over 40 days to win a 1m prize at stake. The 16 competitors are divided into two groups, or tribes, the Helang tribe and the Ular tribe, as soon as they arrive on the island. During each programme the two tribes compete with each other to fulfil a challenge - the Immunity challenge. The two tribes are merged when six competitors have been ejected. When there are just two remaining contestants the Survivors who were voted off return to form a jury which will decided the winner.
Tasks vary but promise to involve mental and physical skills.
The council is formed by the tribe which loses each Immunity Challenge. The tribe must travel to the council through dense jungle before members are allowed to vote. Voting takes place in the form of a secret ballot. The programme is pre-recorded and only the competitors vote. Contestants can form voting alliances but they cannot agree to share the 1m prize.
