A Christian youth group goes for a weekend bonding camp, isolated on an island. Unknown to them, their newest member is a deeply disturbed young woman with a dark past, Mara. She begins to open up to the group, and a young man, David, in particular. She reveals that she used to hear the voice of God, but it stopped after recent traumatic events in her life. The Pastor and the group decide to re-baptize Mara. As a result, Mara is delighted to hear that the Voice has returned, and once again, demands that those around her pay the highest toll for their sinful ways. The group’s only hope is that David can get through to her before they are all “punished”.
