The film is adapted from a true story. Colton Pope (Connor Corum), the three-year-old son of American pastor Todd Pope (Greg Kinnear), had a ruptured appendix and was in critical condition in the hospital. After a series of emergency treatments, little Colton finally came back alive from the gates of hell. As Colton gradually recovered, the family began a peaceful life again. One day, Colton inadvertently mentioned his grandfather who had passed away for many years. Colton was not born when his grandfather passed away, which shocked his father Todd. Not only that, he also told his mother Sonya Pope (Kelly Reilly) about his unborn sister, and his mother had never told anyone about this miscarriage. Little Colton also said that in heaven, he was sitting on the lap of God Jesus, telling him not to be afraid. This bizarre and mysterious miracle was recorded by his father and written into a book, which topped the bestseller list in the United States for 7 consecutive weeks and has been printed in more than 1 million copies. The film is based on the New York Times bestseller novel of the same name.
