Regeneration

Ceres1 is a story about a group of friends, all professionals in their fields, who are invited to take part in a ground-breaking discovery on an uncharted, remote tropicalisland by an English agricultural giant. Each of them have their own reasons for accepting the invite, be it redemption, fame or their own curiosity. 

When they arrive, they find a paradise-the waters are clean, the air is fresh and the people are friendly. After a few days, however, the friends find that they are pawns in a much larger plot and their lives will never be the same again. Now they must fight to regain who they were by being who they are now.
