On a stormy Halloween weekend, Ray enlists his best friends Joaquin, Sofia, and Isabella to help him make a documentary of Malicia, the abandoned theme park off the coast of the Dominican Republic where his mother and brother died in a mass killing thirteen years ago.

But what should be an easy weekend trip quickly turns into something darker because all four friends have come to Malicia for their own reasons:

Ray has come to Malicia to find out the truth of the massacre that destroyed his family. Isabella has come to make art out of Ray's tragedy for her own personal gain. Sofia has come to support her friends in one last adventure before she goes to med school. Joaquin already knows the truth of the Malicia Massacre and he has come to betray his crush Ray to the evil that made the park possible.

With an impending hurricane and horrors around every corner, they all struggle to face the deadly storm and their own inner demons. But the deadliest evil of all is the ancient malignant presence on the island.
