Kim pushes Kendall to breaking point trying to help her modelling career in New York. Kris and Scott come to blows.

Kourtney's resentment towards her mom rises to the surface again after Kris releases a memoir detailing the affair that destroyed her first marriage. Unable to keep her attitude (and pregnancy hormones) in check, Kourt's nasty digs and comments toward Kris reach a whole new level, forcing her sisters, and even Scott, to confront her behavior. Will she get to the root of her anger and forgive her mom? Meanwhile, Kendall and Kylie start their gig at "Seventeen" magazine, but the job causes a rift between the usually close sisters.

Kris does the unthinkable when she goes behind Bruce's back and meets up with her ex Todd Waterman. Will Bruce believe that it was just an innocent dinner? Watch as Kim, Kourtney and Khloe take matters into their own hands and hook their mom up to a polygraph machine to find out the truth! Meanwhile, Lamar gets dragged to the dentist and Rob gets paranoid about going bald.

When the girls find out how serious their grandmother MJ's illness has gotten, they urge Kris to pay a visit. But the thought of seeing her mom brings up a lot of emotions for Kris, who tries to use her busy schedule as a way to dodge the trip to San Diego. Meanwhile, despite her sisters' trepidation, Kourtney mulls over having her baby at home, and brings Khloe along to witness an actual water birth.

Kris sees "Chicago" in New York and is officially bitten by the Broadway bug. She throws all her energy into dancing and singing lessons, but her daughters are less than supportive. Is she willing to dedicate herself fully to a wild new endeavor? Meanwhile, Khloe tires of living out of her car and crashes in Rob's new condo. It's not long, though, before the siblings butt heads. Plus, Kourtney busts Scott trying to make a secret appearance at a Vegas strip club!
