At the heart of the narrative lies Sophie, the spouse of affluent venture capitalist James, whose life is the epitome of envy for many. Residing in a commodious San Francisco residence, adorned with an extensive collection of high-end fashion, her obligations are primarily limited to attending numerous formal gatherings. Nevertheless, this young lady starts questioning the genuineness of her seemingly flawless existence. Her skepticism arises from an incident five months ago, when she suffered a head injury while leaping off a ferry, an act she undertook with unclear motives to inflict harm upon herself, resulting in the loss of her memory.
