Cori signs up to take a mission trip to Indonesia during the summer after her senior year of high school. Inspired by happy visions of building churches and seeing beautiful beaches, she gladly escapes her complicated love life back home.

Five weeks after their arrival, a sectarian and religious conflict that has been simmering for years flames to life with deadly results on the nearby island of Ambon. Within days, the church building the team had constructed is in ashes, its pastor and fifty villagers are dead, and the six terrified teenagers are stranded in the mountainous jungle with only the pastor's teenage son to guide them to safety. Ultimately, Cori's emotional quest to rediscover hope proves as arduous as the physical journey home.
