When Maeve - a female college student - sleeps with Charlie, the married man of the host family she is staying with, both sense the deadly curse is closing in on them. Unable to get anyone to believe them, Maeve and Charlie seek out a local history student to help find answers and figure out a way to defend themselves. It all comes undone, however, as several people are horrifically killed by the savage being - one-by-one at a rapid pace.
