IFC has released a rather enticing photo gallery for Plus One, a supernatural thriller from Last House On the Left director Dennis Iliadis and screenwriter Bill Gullo, starring “Pretty Little Liars” babe Natalie Hall and Chronicle’s Ashley Hinshaw.

Plus One is set at the biggest party of the year and finds three college friends struggling to save their relationships and lives after a supernatural phenomenon occurs at the shindig. Co-stars include Rhys Wakefield (The Purge) and Logan Miller (Would You Rather).

The party kicks off on VOD and selected theaters on Sept. 20.
