As Dixon continues to recuperate while receiving strange back pains, Adrianna confides in Annie that she and Dixon are having intimacy issues. Frustrated with Dixon's dedication to his career at the re-opening of Navid and Liam's new nightclub, the Pop Up, Adrianna goes to re-consummate her relationship with Taylor. Meanwhile, Navid hopes to show Silver how successful he's become with the launch of the Pop Up, but he becomes suspicious that Silver and Liam are seeing each other. Elsewhere, Silver continues her secret profession of burlesque dancing as an outlet for her emotions. Lindsey comes to the opening event to discuss Liam's business plan, and their animosity gives way to passion. Navid confiscates a attendee's phone and discovers a video of Lindsey and Liam having sex. Annie grows closer to Colin, but Riley suspects that Colin isn't who he appears to be. Naomi brings Max's former fiancée, Madison, to try to get her to reveal that Alec tried to destroy her own engagement with Max and in the process show Max the type of person Alec really is, but it doesn't go according to plan.

When Naomi is hired by a wealthy client to plan his wedding, Adrianna suggests they take a girls night out to forget their life problems which takes a sudden turn when (in a homage to 'Dude where's my car?' and 'The Hangover'), Naomi wakes up the next with no memory of the night before and finding out she's married. She teams up with Adrianna (who now has blond streaks) and with Silver to retrace the events of the evening before as well as to look for a missing Annie. Silver breaks the pact she made with Adriana and sleeps with Mark. Meanwhile, Dixon (at Mark's suggestion) hooks up with a bar girl to move on only to find out he has feelings for Michaela, as they spend more time together. Elsewhere, Liam secretly discovers that Campbell (whom is the stepson of Sydney) is plotting to frame Navid for the Cronos Society's cheating scam and he decides to socialize with the Cronos group to get close to them in order to find a way to clear Navid's name.
