Muck

A group of friends, including Troit (Lachlan Buchanan), Kylie (Stephanie Danielson), and Chandi (Puja Mohindra), emerge from the marsh after narrowly escaping an ancient burial ground. They take shelter in an empty Cape Cod vacation house, but whatever was in the marsh is still after them, and a more savage threat lies in wait outside. The group spends their St. Patrick's Day trapped between two evils, forced to fight or die, as they try to survive amidst the carnage.
