Six strangers from across the world converge on the tropical island of Bali to attend a course designed to help them face their fears. Their backgrounds are as diverse as their fears - which range from flying, public speaking and heights, through to intimacy, failure and death. Friendships and even romance blossoms as the participants are put through a series of challenges which are unusual, confronting and sometimes hilarious. A week of fun in the sun suddenly tranforms into something far more serious, however, when the unthinkable happens - a tragic disaster that puts the group in deadly danger that will test the individual courage of every member.
