After asking them to each play a note on a piano, he identifies a disconnection in their relationship and suggests they take a weekend on a secluded estate. Once at the estate, Sophie goes to the guest cottage and has sex with Ethan. She returns to the house to find Ethan asleep. When she mentions the sex, he says he cannot remember, so Sophie, annoyed, goes to bed alone and he sleeps in the guest cottage. During the night, Sophie joins him, apologizing for her behavior and falling asleep next to him. The next morning, she makes him eggs and bacon, which is odd, as she notedly hates it. Ethan returns to the main house where Sophie has no memory of joining him in the guest cottage. He deduces that something unusual is going on: In the guest cottage, they each met a doppelgänger of the other, convincing enough to pass. By visiting with Sophie II, Ethan establishes the doppelgängers do not leave the guest cottage. By barging in on Sophie's session with Ethan II, he determines that the doppelgängers disappear when both spouses are in the guest cottage and the doubles are idealized versions of them. Ethan and Sophie take advantage of the circumstances, and set rules, including a rule of "no intimacy". Ethan figures an explanation for what's going on as some of his clothing is missing, and he receives voice mails from friends and family, answering calls, made in his voice, asking about his past. Sophie starts developing feelings for Ethan II and goes to the guest cottage to seduce him. Ethan discovers this by claiming to leave, but instead enters the guest house and assumes the place of his doppelgänger. Sophie seduces the real Ethan, unbeknownst to her. The next morning, Sophie seeks refuge with Ethan II, and Ethan I disturbs them by entering the guest cottage. As they argue, they find Sophie II and Ethan II awaiting them in the main house.
