After a few days of Emily being gone, Stephanie's viewership has increased, and one of Stephanie's vlog viewers sends her a message stating that she may have spotted Emily driving in Michigan. Stephanie wraps up her original video posted after Emily had been missing for five days, updating her viewers with details about Emily's rental car. Detective Summervile (Bashir Salahuddin) later visits Sean to inform him that Emily was not on any flights to Miami but that she rented a car from LaGuardia Airport the day she disappeared. Stephanie then uses the photo of Emily to make missing fliers. Stephanie is spotted on her way out of the office and Dennis threatens her, but Stephanie remembers hearing Emily speaking brashly to Dennis, and Stephanie hits back with some sass of her own to get Dennis to back off. Stephanie sneaks into Emily's office and finds a black-and-white photocopy of an unflattering photo of Emily with 'Gotta have faith' written on it. She goes to Emily's work in New York City and meets her overbearing boss, designer Dennis Nylon (Rupert Friend), who rudely dismisses Stephanie's concerns and insults her outfit. Stephanie takes it upon herself to find out what happened to Emily. The police imply that she has left on her own because of marital troubles and Sean later tells Stephanie that Emily deleted his Facebook account once when he posted a photo of her. He returns home the next day for Nicky, and when Stephanie tells him that her assistant is unable to get in touch with Emily either, they speak to the police about Emily, who has been gone for three days. He says that when Emily knows Nicky is with someone taking care of him, she will disappear for a few days. Stephanie gets in touch with Sean to inform him, and he isn't surprised that Emily has left Nicky with her. Stephanie calls Emily's job and is told that Emily flew to Miami to handle something, which she didn't mention to anyone, even Sean. After two days, Emily hasn't come for Nicky. Stephanie obliges, but she can't get in touch with Emily. Emily calls Stephanie and asks her for 'a simple favor' to pick up Nicky from school because she has to take care of some work business, while Sean has gone to London to look after his injured mother. In her grief, Stephanie turned to Chris, and the two wound up having sex, leading a shocked Emily to call Stephanie a 'brother fucker'. Stephanie then tells a secret of how, after her father passed away when she was a high school senior, she met a son he had from another relationship named Chris (Dustin Milligan). Emily tells Stephanie of how she and her husband got into a threesome with Sean's teaching assistant a few months earlier. At Emily's house, the two have martinis and trade secrets. Emily firmly orders Stephanie to delete the photo, and does not explain why. While taking the boys to the park, Stephanie snaps a photo of Emily for the school's yearbook.

However, when Sean isn't there, Emily notes that Sean hasn't written a thing since the first book 10 years ago, and that they are close to bankruptcy. Stephanie says she has read Sean's book and enjoyed it. Emily's husband, English professor and one-time author Sean Townsend (Henry Golding), arrives home and meets Stephanie while he and Emily kiss passionately. Stephanie explains that she is a widow after her husband and brother were killed in a car accident. Emily is blunt and rather crass, even telling Stephanie to stop apologizing. She is stunned to see a graphic nude painting of Emily hanging on a wall. Stephanie arrives at Emily's stylish home. Stephanie first meets the sophisticated Emily when she goes to pick Nicky up, and, at the boys' pestering, Emily agrees to the playdate and invites Stephanie to come over for drinks. After school, Miles wants to have a playdate with his friend Nicky (Ian Ho), Emily's son. The other parents discuss their jealousy over Emily, who works in New York City for a major fashion brand as a public relations manager. Stephanie is always volunteering and contributing to Miles' (Joshua Satine) class, to the point where some other parents like Darren (Andrew Rannells), Sona (Aparna Nancherla), and Stacy (Kelly McCormack) think Stephanie is making them look bad. Stephanie admits she has not known Emily that long, and met her at their sons' kindergarten recently. Stephanie is overcome with emotion before composing herself to give new viewers a recap on what has happened. Mommy blogger Stephanie Smothers (Anna Kendrick), a single mother in Connecticut, makes a video for her mom vlog, 'Hi Moms!' Before she begins with her recipe, she updates viewers on an ongoing case involving Stephanie's best friend, Emily Nelson (Blake Lively), who has been missing for the last five days.
