The holiday season is approaching and Sam and Charlotte Cooper are planning a big, four-generation family reunion at their house for Christmas. What the others don't know is that the couple has decided to end their marriage after forty years, but they're keeping it a secret until the one last big holiday celebration is over. The other family members are going through their own problems. Their son Hank is a recently divorced single parent of three children, while their daughter Eleanor brings a fake boyfriend to the family dinner. Charlotte's father and sister, as well as Sam's aunt are also joining.
