Mae is restless in a life and marriage that works. There is love between her and her husband, but little romance. When Mae "slips" and has a one-night stand with Eric, a handsome man she meets at a bar, she wakes up the next morning in a panic, only to realize she's entered a parallel universe in which she and Eric are married. This is the start of her surreal journey as she slips into other realities and relationships, trying to find a way back to her husband, and ultimately, herself.
