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 Khloé struggles being away from her hubby, her commitment to the DASH store and even her Khloé 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 Khloé clash during a sexy DASH photo shoot.
