Meanwhile, Khloé jets off on a romantic getaway to South Africa with her new boyfriend, French Montana.

Scott finally decides to make a change in his life and checks into rehab, but his commitment to stay wavers with each day. Meanwhile, as her 30th birthday quickly approaches, Khloé struggles with the realization that her life isn't where she imagined it would be.

Meanwhile, when Kourtney proclaims that she is a trained sailor, Khloé and Scott decide to test her skills on the open water.
