“All families have secrets. These are ours.”

Marge Cosgrove sold her house in Pittsburgh and is moving to NYC to be closer to her choreographer son Randy, his husband and her grandchild. While taking one last sweep of the now empty house to see if she left anything behind, Marge finds an envelope containing the Christmas Letters she had written to friends and family over the years. When Randy zooms in to get one last look at the place, Marge learns her flight has been delayed. So she fills the time to read some of the letters to Randy and in the process reveals stories and surprises about their family he never knew and some he wish he never did.
