Their relationship on the rocks, a young Brooklyn couple heads to a remote B&B to work things out. But from the moment they arrive at The Happy House it's one disaster after another, and they soon begin to suspect they've wandered into a real life horror movie. Events escalate from weird to terrifying as they contend with the house's batty owner, her imposing son, a moody Swedish lepidopterist, a pedantic English professor, an extraordinarily rare butterfly, the world's best blueberry muffins, a .44 Magnum, a demented serial killer, and one very strict rulebook.

On a trip to Big Sur, two friends, both actresses, try to reconnect with one another. Once alone, the women's suppressed jealousies and deep-seated resentments begin to rise, causing them to lose their grasp on not only the true nature of their relationship, but also their identities.
