The film is based on the book
Two Kisses for Maddy: A Memoir of Loss & Love by Matthew Logelin, and is described as a “heartwarming, funny, and emotional true story” where Hart “takes on the toughest job in the world: Fatherhood.” The book’s synopsis offers some more insight:
Matt and Liz Logelin were high school sweethearts. After years of long-distance dating, the pair finally settled together in Los Angeles, and they had it all: a perfect marriage, a gorgeous new home, and a baby girl on the way. Liz’s pregnancy was rocky, but they welcomed Madeline, beautiful and healthy, into the world. Just twenty-seven hours later, Liz suffered a pulmonary embolism and died instantly, without ever holding the daughter whose arrival she had so eagerly awaited. Though confronted with devastating grief and the responsibilities of a new and single father, Matt did not surrender to devastation; he chose to keep moving forward-to make a life for Maddy.
