Kourtney & Khloe Take Miami

The Kardashian sisters head back to South Beach and drama isn't far behind! In this sizzling new season, Kourtney and Khloe return to Miami to revamp their struggling DASH boutique. This time, Kourtney brings her beau Scott and baby son Mason along for the ride as she tries to breathe new life into the store--including hiring an all new staff! But when Khloe ends up postponing her trip to be with husband Lamar, Kourtney ends up doing most of the hard work herself and starts to question whether Khloe should really be involved. Meanwhile, as Khloe struggles being away from her hubby, her commitment to the DASH store and even her Khloe After Dark radio gig comes under fire when she can't seem to focus on her responsibilities. Plus, things get extra heated when Kourtney and Khloe clash during a sexy DASH photo shoot.

Khloe is excited that her husband Lamar is coming to visit her in Miami and she wants to make sure she looks absolutely perfect--including down there! So when Khloe doesn't have time to get her usual bikini wax done, she agrees to let Kourtney do it for her, but Khloe is mortified when Kourtney ends up doing more harm than good. Not only does Khloe end up in pain, she's also worried that her one night with Lamar in Miami is ruined. Meanwhile, when Kourtney's old friends come out to visit, she decides to let loose and party like the old days--but when the reality of motherhood settles in, she is reminded that times have changed.

While Kourtney and Mason are out of town, Scott's pals from New York come visit and bring out his bad boy ways. When Kourtney tells Scott she doesn't want him to mix her personal life with her employees, he agrees but eventually crosses the line by inviting the Dash girls to his club opening and disrespecting them in front of his friends. When Kourtney finds out, she confronts Scott about not respecting her wishes. Meanwhile, after a fascinating interview with a forensic specialist, Khloe's obsession with serial killers grows and she starts to accuse Scott of being a sociopath, but her playful innuendos go too far when she puts Scott at risk of losing his job.

When a polo instructor starts flirting with Kourtney, she is disappointed Scott doesn't step in and starts to wonder if they've become too comfortable in their relationship. In an effort to keep him on his toes, Kourtney invites her old Miami flame Jackie over to the apartment to make Scott jealous, but her plan backfires when he unexpectedly turns the tables on them. Meanwhile, Khloe heads back to Los Angeles to spend a few days with her husband Lamar, but she becomes annoyed when Lamar spends his time with her brother Rob.

When Khloe returns to Miami, she vows to take more responsibility at Dash and offers to watch over the store while Kourtney prepares for a post-baby magazine photo shoot. The pressure to look bikini ready pushes Kourtney over the edge and she resorts to extreme dieting and excessive exercise to try and get back her pre-baby figure. Eventually, the stress of the shoot sparks a fight between her and Khloe that could change their relationship forever, resulting in Khloe leaving Miami to return to her husband Lamar in Los Angeles.

With Khloe gone, Kourtney is left to run the Dash boutique in Miami by herself. Knowing Kourtney also has to take care of her baby Mason, Kim takes the first flight out to help fill the void and reconnect with her sister. But the plan turns sour when Kourtney sees Kim is constantly distracted by her BlackBerry. When she takes away Kim's phone and computer, will Kim be able to unplug completely for an entire weekend? Plus, Kim reveals the reason she and Reggie Bush finally broke off their relationship for good, and one of the Dash dolls has an STD scare.

Is Scott a changed man or is he back to his hard-partying ways? Kim is worried Scott is spending too much time drinking at Miami clubs and not enough time with his girlfriend and newborn son. When Kim brings up the issue, Kourtney gets defensive and aggravated that her family has never accepted Scott. But when two bottles of Kim's wine go missing, Kourtney is forced to confront Scott about his demons. Meanwhile, Kim is excited to baby-sit Mason while Kourtney is at work, but can she handle the diaper changes, burping, and baby puke? Find out.

Scott's hard-partying ways finally catch up with him during an aggressive rage in front of Kourtney. Frightened by this violent side of Scott, Kourtney leaves the apartment with Mason and refuses to see Scott until he seeks professional help. But when Scott calls on Kourtney in his time of need, will she stand firm by her decision or will she crumble and come to his aid? Meanwhile, Kim has a hard time coming to terms with her breakup with Reggie Bush and fears she won't be able to find a partner who can accept her Hollywood lifestyle.

The family drama really heats up when Kris comes to visit Kourtney in Miami and starts meddling in her relationship with Scott. Kris feels it's her motherly duty to tell Scott to stay away from Kourtney and Mason, but will her plan backfire and push Kourtney to reconcile with Scott instead? Meanwhile, Khloe returns to Miami to help out Kourtney, but she finds out that firing an employee is hard to do when she has to let one of the Dash dolls go.

As their time in Miami comes to an end, Kourtney must decide if Scott will come back with her or go back to his home in New York. Even though she hasn't seen Scott face-to-face since his violent outburst, Kourtney agrees to go to a therapy session with him to show her support, but ends up more confused than before about whether or not Scott should be in her life while he works on his own issues. When Scott refuses to abide by Kourtney's rules and boundaries, she flies back to L.A. without him. Meanwhile, the sisters say goodbye to the Dash dolls and Khloe wraps up another season of her Miami radio show "Khloe After Dark."
