The Moodys gather in their hometown of Chicago for the “perfect” holiday. From break-ups to arrests to sharing one bathroom, each family member is packing his/her own eccentricities and hiding secrets from the others – as if the holidays were all about carols and eggnog!

The season picks up with Sean Sr. contemplating retirement - road trips across the country in an RV with Ann, while Sean Jr. takes over the family HVAC business. In reality, however, Ann has no intention of leaving her new psychology practice, and Sean Jr. continues to brew up schemes to get rich quick. Bridget, who is in the midst of a divorce, returns home while her fancy new townhouse is being renovated; and Dan leaves Brooklyn for Chicago to live with his girlfriend, Cora, only to realize the relationship is moving too quickly. Once again, the Moody's are all under the same roof. Yep, one big, happy family.
