After a string of traumas, Catherine (Elisabeth Moss) retreats to a bucolic lakeside cabin with best friend Virginia (Katherine Waterston, Inherent Vice) for some rest and relaxation. But as festering anxieties come bubbling to the surface, boundaries between past and present-and sanity and madness-begin to collapse, and Catherine veers perilously closer to the edge. Shot on gorgeously ragged 16mm, Perry's (Listen Up Philip) latest updates '70s psychological horror with a very modern intensity.
