Complete listed story — includes the ending

1. A Danger to Himself and Others

Picking up on the day after Season 3 ended, Romero disposes of Bob Paris' body in the bay. With Norman missing, Norma and Dylan worry about his well being. A farmer discovers an unstable Norman, resulting in him being admitted to a psychiatric unit. Meanwhile, Dylan goes to Portland to be by Emma's bedside after her lung transplant, while Norma attempts to have Norman discharged from the institution. The psychiatric doctor refuses to let Norman leave until after a 48-hour observation period, and chastises Norma for never taking Norman to a doctor for his frequent blackouts. Desperate, Norma returns to Pineview Mental Hospital hoping to have Norman admitted as soon as possible and encounters a psychiatrist, Dr. Edwards. Since she doesn't have insurance, Norma asks Romero to marry her so she can use his, but he rebuffs her. Elsewhere, Emma's estranged mother, Audrey, attempts to make contact, but Emma's father turns her away. As Audrey seeks help from Norman, "Mother" strangles her to death with her own scarf.

2. Goodnight, Mother

Norman tries to remember what happened the night before. He then has flashes of "Mother" hiding Audrey's body in the basement freezer. Meanwhile, Emma breathes freely for the first time with her new lungs without her oxygen tank, to the relief of Dylan and her father. Meanwhile, Romero visits Pineview with the money for Norman's admission. However, because Norman is 18-years-old, the institution needs to have his signature on consent forms. Norman accuses Norma of killing Audrey, alerting his mother to the fact he committed another murder. She searches the motel's pit for a body, but only discovers a glove. Norman later finds the Pineview forms in the motel's fax machine. He then has a vision of his deceased father, who tells him that Norma is the one who killed him and that she is trying to blame Norman for all the killings. Norman's behavior scares Norma, who flees from him and calls Romero for help. With his mother's gun, Norman alludes to the pair committing suicide since they can't be happy in life. Romero arrives at the Bates residence, and Norma convinces Norman to sign the consent forms before he is taken away to the Pineview hospital.

3. 'Til Death Do You Part

Norma and Romero get married, and afterward, Romero moves into the Bates house in order for their relationship to look real. Romero has the pit filled in as a wedding gift, but a worker discovers one of Audrey's earrings at the site, distressing Norma. Meanwhile, Dylan returns to White Pine Bay to fire Gunner and get out of the drug trade, but arrives at the farm to find Gunner quitting instead. Chick arrives at Dylan's farm looking for revenge on Caleb, but Dylan informs him he hasn't been in contact with his father since he skipped town. At the Pineview asylum, Norman has his first therapy session with Dr. Edwards, who presses Norman to share his concerns about his mother. Norman is conflicted as both hiding and telling the "truth" would cause problems for Norma. Later, Norma visits Norman, and the two have a heated exchange in front of staff and other inpatients. Elsewhere, Romero's ex-girlfriend, Rebecca, visits him, worried that her part in Bob's money laundering scheme may come to light. Romero tells her to keep her head down and she'll be safe from suspicion.

4. Lights of Winter

Norman and fellow patient Julian plan an escape from Pineview. Meanwhile, Norma and Romero become closer in their sham marriage, and he suggests opening a joint bank account to make it appear more legitimate. He then gets an urgent message from Rebecca, who later tells him Bob Paris has $3 million in a safety deposit box, to which Romero finds the key. Norma visits Emma in the Portland hospital, who tells her to start living her own life and to not worry about Norman. Emma also plans to move to Seattle and asks Dylan to move with her. After attending a carnival with Romero and awkwardly meeting Rebecca, Norma and Romero return home to find the house ransacked. Meanwhile, Norman and Julian escape from Pineview and hitch a ride to a strip club. Julian gives Norman some money, and both are taken separately to private rooms. While alone with a dancer, "Mother" appears, but the two are interrupted by a fight between Julian and some bouncers. This leads to Dr. Edwards arriving to collect Norman, who breaks down and accepts Dr. Edwards' help.

5. Refraction

Norma and Romero begin cleaning the house, and she is upset about her favorite stained-glass window being broken. Romero mentions that things like that happen "when you're married to the sheriff". He later cautions Rebecca, whom he knows broke in, to stay away. Norma asks in town about a glass repairman, and Chick Hogan arrives at the house for the job. He later learns that Caleb is Norma's brother. Meanwhile, Dylan takes Emma home to White Pine Bay, but later goes to Seattle for a job interview. At Pineview, Norman begins his therapy sessions with Dr. Edwards and seems to be open with most subjects, except that of his father. He calls to leave an apologetic voicemail with Norma, who later visits him at the institution; Dr. Edwards later suggests the visit was all in Norman's mind, which is confirmed when Norman gets agitated and "Mother" starts talking with the doctor. Also, Chick returns to see Norma and says he previously met Caleb, who was introduced as Dylan's father. He tells Norma of his hatred for Caleb and asks her to decide her brother's fate.

6. The Vault

Norma meets again with Chick, who threatens to publicly reveal her past with Caleb and, ultimately, ruin her marriage to Romero. This sets off a sense of urgency in her, in which she manages to get Caleb's possible location from Dylan. She contacts Caleb, but later tells Chick to do his worst in destroying her life. Meanwhile, Romero gives the safety deposit box key to Rebecca, adding that he wants none of the money in return. At Pineview, Dr. Edwards explains dissociative identity disorder to Norman and that the "Mother" persona is what arises during his blackouts. Norman recalls when he was age seven and Norma tried to leave his drunken father. She was raped while Norman hid under the bed. Dr. Edwards asks to speak to "Mother", who warns him to not allow Norman to recall memories that will hurt himself. Chick delivers the window with Romero's help. Norma then explains Chick's true intentions and tearfully reveals her past to Romero, believing he will leave her as a result. Despite the truth, Romero decides to stay married to Norma.

7. There's No Place Like Home

Norma tells Romero about her dream to renovate the Bates house, but her financial position won't grant her the opportunity to do so. Romero reveals to her the money he took from Bob on the night of his murder, offering it so she can begin making her dream a reality. While at Pineview creating papier-mâché, Norman finds a newspaper clipping about his mother's marriage to Romero. Norman calls home to hear Romero answer the phone and Norma lie regarding his reasons for being there. Norman then sets into motion his plans of going home. Meanwhile, Dylan investigates Audrey's disappearance when Emma loses contact with her. He shows Norma the letter of Audrey's found in Norman's room, confronting her about why it was in Norman's possession. Dylan later gives the letter to Emma, who ultimately decides that her mother's vanishing is an act of desperation. Despite Dr. Edwards' and Norma's efforts to keep Norman at Pineview, he is released and returns home.

8. Unfaithful

Romero stays away from the Bates house to help Norman adjust to a normal life. Norman soon tells him of plans to get a second job to pay for his own insurance in order to let Romero out of his arranged marriage to Norma. Romero tells her that Norman needs to be told that they're in love. Meanwhile, Rebecca is picked up at the airport by the DEA, but is told they are actually after Romero in connection with Bob Paris. At the Bates house, Norma, Romero and Norman have dinner together. Norman gets into an argument with his mother over her allowing Romero into their lives, when she and Norman were so close to the point of him not being able to have girlfriends. Norman storms out to chop wood in anger; Romero follows. Norman approaches him with the axe, but destroys a shed and proclaims that he hates Romero.
