Relationship expert Dr. Jenn Berman and her staff of therapists welcome the celebrity couples to an intense program designed to fix even the most troubled relationships.

On the first night of Couples Therapy, the drama surrounding Courtney Stodden and Doug Hutchison’s controversial marriage continues when Doug demands an apology from Nik for calling him a child molester.

Continuing from the previous episode, Berman convinces a distraught Shayne to stay. In Process Group, Berman talks to the couples about the lies that they have used to maintain lives as public figures. Nik apologies to Doug for his prior language, but tension between them continues. Tiny attempts to talk to JoJo about his alcoholism, but he dismisses her concerns. Alex McCord and Simon van Kempen explore their relationship problems, but end up fighting over them. Berman and Tom Carouso observe communication difficulties in Alex and Simon, who bicker over minutiae but do not discuss specific issues regarding their relationship, and Doug and Courtney, who have trouble speaking due to Courtney's tendency to become distracted. Todd struggles with whether he can maintain his public image as a womanizer while staying in a committed, monogamous relationship.

Because of the limited amount of time that Courtney, a minor, can legally be allowed to spend at the treatment center, Doug must do without her during a couples yoga session, which causes him to become upset. Berman speaks to the group about trust, during which Courtney reveals that she still desires friendship from her ex-boyfriend, but romance from Doug. Dow and Berman talk to Tiny and JoJo about his alcoholism, but JoJoe remains obstinate.

Nik threatens to leave therapy because he feels Shayne is isolating herself and unwilling to take part in the process. Doug and Courtney get a wake-up call when Dr. Jenn decides to implement a new house rule.

During an intense process group focused on childhood trauma, Alex and Tiny share their heartbreaking stories, but when Courtney refuses to be authentic about her own experiences, the group gangs up on her out of frustration.

With Doug and Courtney gone, the rest of the couples rejoice, happy to be free of the constant drama.

Courtney and Doug return to the house, and although they swear that they are returning with an open heart, not everyone in the house is buying it.

With only two days left until the couples complete therapy and leave the house, Dr. Jenn and her staff work frantically to tie up any loose ends. One of the couples decides to reaffirm their love with an unexpected wedding.
