Antibirth Poster

InAntibirth, trailer dweller Lou (Natasha Lyonne) and her best friend, Sadie (Chloe Sevigny), spend most of their nights steeped in a murky haze of pot smoke and booze-filled TV-watching sessions, venturing out on occasion to party in a desolate community full of drug-addled ex-Marines and other miscreants of society. After an otherwise normal night of self-destructive behavior, Lou awakens with symptoms of a bizarre illness and psychosomatic, recurring visions that she can’t seem to shake. Unfazed, she continues with her hard-living ways, but even her frequent bong rips don’t fully explain the shitstorm swirling around in her head.

Without being able to remember anything from the night before, she struggles to get a grip on the reality of her situation as unusualconspiracy theoriesbegin to arise. As her symptoms grow at a rapid pace, something otherworldly has infected her body, and try as she might, it refuses to be ignored.Antibirthis produced byCole Payne,Roger Meyer,David AnselmoandJustin Kelly, withNatasha Lyonnealso producing.
