Spiaggia Resort

The senior class of Westwood Highschool are taking their final vacation field trip to the Spiaggia Resort in Hilton Head Island, South Carolina. While staying at the resort, the seniors experience terrible things; death, and murder. One by one, each of the twelve students in the group (who happens to be staying in the same building) begin to disappear. Who is the murderer? And what is their motive?
