Business is booming for Bethenn,y but not quite fast enough when it comes to the growth of the Skinnygirl Margarita. When Bethenny realizes that liquor stores are unable to replenish their supply quick enough, she enlists Jason to help to figure out the problem. But it's a precarious position for Jason, as he understands Bethenny's fiery nature and wants to make sure he doesn't get burned in the process. When Bethenny then faces the consequences of her boundary issues with other important people in her life, namely her intern Max and her broken-hearted baby nurse Gina, she realizes she must find balance in all of these relationships before things spiral out of control.

Bethenny's 40th birthday party is around the corner and everyone wants to celebrate. Everyone, that is, except Bethenny. After some cajoling by Jason, friends, and her former wedding planner Shawn, Bethenny goes against her best instincts and agrees to a party. But just as party plans get underway, Bethenny receives a call asking if she wants to compete on the new show Skating with the Stars. Could this invitation be just what the doctor ordered? Is skating just what Bethenny needs to escape the birthday blues and recapture her youth?
