A father and daughter accidentally hit and kill a unicorn while en route to a weekend retreat, where his billionaire boss seeks to exploit the creature's miraculous curative properties.

With her laundromat teetering on the brink of failure and her marriage to wimpy husband Waymond on the rocks, overworked Evelyn Wang struggles to cope with everything, including a tattered relationship with her judgmental father Gong Gong and Joy, her daughter. And, as if facing a gloomy midlife crisis wasn't enough, Evelyn must brace herself up for an unpleasant meeting with an impersonal bureaucrat: Deirdre, the shabbily dressed IRS auditor. However, as the stern agent loses patience, an inexplicable multiverse rift becomes an eye-opening exploration of parallel realities. Will Evelyn jump down the rabbit hole? But how many stars are there in the universe? Can weary Evelyn fathom the irrepressible force of possibilities, tap into newfound powers, and prevent an evil entity from destroying the thin, countless layers of the unseen world?
