Escape to paradise.
Scuba diving instructor Cass leads her students out for their first dive off the beautiful coast of Koh Sang, Thailand's world-famous party island. It's supposed to be a life-changing experience, but things quickly spiral out of control...

Leave your secrets behind.
By the time she gets back to the shore, one of her students is dead, another badly injured, and she knows that her idyllic life is about to be smashed to pieces on the rocks.

But don't get lost for ever...
Someone has discovered Cass's secret, and on an island as remote as this, accidents happen. Plenty of backpackers choose to stay here for ever - but some are never heard from again...
