The Noel Diary is based on The New York Times bestselling novel of the same name by Paul Evan about a man, Jake Turner, who gets the chance to re-write his history one Christmas after his estranged mother passes away.
Days before Christmas, Jake receives a call from a lawyer informing him of the demise of his estranged mentally ill mother and that she left her house to him. Jake returns home to settle the estate, and while decluttering the house, he finds a diary belonging to someone called Noel, a young lady who used to care for Jake's mother.
Jake gets an unexpected visitor, a woman searching for her mother, who put her up for adoption when she was a child. The two embark on a quest to find Noel, who can help answer their questions. As they journey to find themselves, they find each other as well.
