Ludlow(2010)

Krista (Shannon Lark) leaves her boyfriend behind and drives to a rundown desert motel to await the arrival of her sister Maddy (Elissa Dowling). Broken and abused, Krista downs prescription pills and cheap vodka to forget her troubled past. As she sits alone in the motel room, her grip on reality lessens until neither Krista nor the viewer can tell what's real and what's not.
