A tight-knit but slightly dysfunctional family of five gather in their hometown of Chicago for the โperfect'' holiday. From break-ups to arrests to sharing one bathroom, each family member is packing his or her own eccentricities and hiding secrets from the others -- as if the holidays were all about carols and eggnog. The family includes Sean Sr., his wife, Ann, and their three grown children -- Dan, the youngest of the siblings and the โcreative one''; Bridget, the middle sister and the โoverachiever''; and Sean Jr., the oldest sibling and โscrew-up,'' still living at home with his parents.
