Irrationalia

When three friends receive a startlingly incoherent invitation to a "Reeyoonyun" they seize upon it to break up the monotony of their middle-aged lives. The host, one of their old friends, seems battered and out of it. The maid acts like a weird robot. The host confesses the house might not actually be his. Over the course of a tense, bizarre evening, the friends soon realize the invitation was to something much more sinister than a reunion: the past.
Twenty-five years ago, in 1993, the group experienced something on a summer night in the woods. They've done their best to forget about it but the repercussions of it have sent shockwaves through each of their lives. Now they must decide if they want to leave the past buried or dig it up and confront it and all of its mind-bending, life-altering horror.
