In the first episode of the third season of Bravo's The Real Housewives of Orange County, Vicki surprises daughter Briana with a brand new Mercedes, literally wrapped up in a bow. Briana is now living on her own as she goes to college and Vicki has learned that with both kids out of the house, the only way she can maintain any control over them is with money. Lauri is awash in wedding plans as her upcoming nuptials to George consume her every thought and deed. George's eldest daughter, McKenzie, is about to graduate from high school and hopes desperately to get a trip to Miami Beach as her graduation present. A major tragedy has befallen Tammy and her daughters, Megan and Lindsey. Their father (and Tammy's ex-husband) Lou Knickerbocker, recently died of a heart attack. Without a will to provide for them, Megan and Lindsey are now forced to fend for themselves while Lou's young widow gets everything he had. Lindsey - who was living with Lou at the time of his death - was kicked out of the house by Lou's young wife, leaving her no choice but to move in with sister, Megan. They both live above Tammy's water damaged home, which is under renovation. Their future is uncertain and their lives will never be the same again. Meanwhile in the Keough household, Jeana's daughter Kara is graduating from high school and planning a graduation party. Younger brother Colton is becoming more like his older brother Shane as his antisocial behavior escalates. Newly single Kara (recently broken up with boyfriend Steven) is devastated when Colton doesn't show up for her graduation. Shane leaves to play minor league baseball in Canada. Newest and hottest housewife Tamra - on the verge of turning 40 - is a realtor and mother of four. Her eldest son, Ryan, whom she had when she was only 18, is from a previous marriage. The 21-year-old moved out of the house when he turned 18 because of tension between himself and Tamra's current husband, Simon. But now that he's moving back home, sparks are about to fly, with Tamra caught in the middle.
