Sarah Douglas wants to throw a party since her old friends are in town for Thanksgiving, and, okay, maybe to show off her swanky new house and prove to everyone (including her skeptical parents), that she is a grown up. With the help of her best friend, Jake, she is determined to make this Drinksgiving the best one ever. She soon finds out that growing up is not the same for everyone. The parade of guests include some folks Sarah knows, but many she doesn't, including Joe, who brings a bag full of chili fixings. Then there is Aimee, Sarah's 'frenemy', Mandy who looks stuck in the 90's, choker necklace and all, pot-dealer Kyle, and finally, Sarah's best friend, Kelsey. When Kelsey reveals that she is not only engaged, but that her new beau, Lucas is an adult film star, Sarah's idea of growing up is washed away. Now, she must contend with the motley bunch of guests, Jake's personal needs, and Kelsey's reveleations, while maintaining her 'grown up' party.
