Sarah (Alison Brie), a socially isolated arts and crafts store employee, finds herself more content in the company of horses and supernatural crime shows than people. But when a series of strangely surreal dreams upend the simplicity of her waking life, Sarah struggles to distinguish her visions from reality. Directed by Jeff Baena, Horse Girl is a darkly humorous psychological thriller about a woman's search for the truth, however abstract it may be.
