IFC has acquired US rights to Dennis Iliadis’ supernatural thriller “Plus One” three months after its premiere at South by Southwest.

The film stars Rhys Wakefield (“The Purge”) with Logan Miller, Ashley Hinshaw and Natalie Hall. Tim Perell produced.

Script, written by Bill Gullo and based on a story by Iliadis, is centered on three college friends who go to the year’s biggest party. When a mysterious phenomenon disrupts the party, it quickly descends into chaos.

The executive producers are Brothers Strause, Edson Williams, Thomas Nittmann and Guy Botham. Lola/Hydraulx  provided the VFX for the film.

Deal was negotiated by Jeff Deutchman for Sundance Selects/IFC Films with CAA on behalf of the filmmakers.
