[2] Jeff (Jason Ritter), a Wall Street power broker going through a slump in business and relationship, and Marla (Emmanuelle Chriqui), a party-loving Princeton graduate, are siblings.

Their father Ed (James Brolin) is a wealthy old man who has remarried and moved to Lake Country in Ontario, Canada.

The siblings resentfully arrive with their Dad's lake house to meet his new wife, an ex-waitress, Sherry (Christine Lahti) and her children: redneck David (Benjamin Arthur) and his wife Tammy (Kate Corbett), failed musician Keith (Steven McCarthy) and academically inclined Sam (Vinay Virmani).

Ed and Sherry announce their plans to adopt a child in an attempt to gel the new family together.

The movie attempts to portray a comic clash between two cultures and two families which quickly descends into chaos.
