Jeff Lewis and his staff: Jenni, Zoila, Sarah, Jett and Trace are back for the fourth season of Bravo's "Flipping Out." With Ryan out of the picture and the drama put behind them, Lewis and his crew are busier than ever. But, focused on growing Jeff Lewis Designs and keeping up with his demanding clients, Jeff wastes no time trimming the fat off his business. Unfortunately for his staff, this might mean them.

Blood may be thicker than water, but Jeff doesn't spare his sister-in-law/assistant, Sarah any slack. After a year of working with Jeff, Sarah still struggles with daily tasks and Jeff thinks a little tough love would go a long way, so he enlists her in his own Jeff Lewis version of assistant boot camp. Meanwhile, Jenni nearly brings down the roof, literally, at one of Jeff's most important clients.

After dealing with several client issues, Jeff realizes that his real bread and butter lies within his clients' happiness and he suddenly decides to focus on customer service and professionalism - two things that do not come easy to Jeff. With this new agenda in mind, he brings Trace and Sarah with him on a business trip, but before they go, they need to get to the bottom of a very concerning pet issue.
