For her graduation present, George’s daughter McKenzie hits the sun and fun of South Beach, Miami along with Tammy’s daughters, Lindsey and Megan, and Lauri's daughter, Ashley. Money woes put a damper on the Knickerbocker girls’ good time and a trip to a famous tattoo parlor gets McKenzie in hot water with dad George. Vicki invites Jeana, Colton, Tammy and Frankie to spend the weekend with her and Donn at their Lake Havasu vacation home. The alcohol flows like the river on which they party, but tensions between Vicki and Donn threaten to ruin the trip. Things turn dangerous when Colton takes a shocking death defying jump. Laurie furthers her wedding plans by choosing a photographer and wedding invitations, while newly single Kara contemplates an offer from mother Jeana to take part in a mother/daughter pictorial for Playboy magazine. Tamra throws a big birthday bash for son, Spencer, who just turned seven. The party atmosphere can't tame the tension between her oldest son, Ryan, and her husband, Simon.
