Once upon a midnight dreary.

In this update to Edgar Allan Poe's classic tale, it's time for the biggest gay party of the year. Unfortunately, the host has chosen the site of the infamous Ravenswood Massacre to stage his blowout gala, where a mass murder happened fifty years ago to the night. The boozie revelry is cut short when a Raven-masked killer crashes the party, intent on repeating the bloody history. As the unknown killer picks the guests off, old grudges resurface among friends, and new suspicions emerge.
