Josh McDowell is a writer and a public speaker who touches on aspects of familial relationships and Apologetics (the defending of Christianity) in general. This autobiographical film was based on his early life and explained his motivations behind what he does in his professional life.
The film was screened after a seminar he had given at a church near where I lived, while the audience didn't get to have a chance to speak to or have an interactive session/Q&A with Josh McDowell himself before he left, the film itself answered on why the person himself devoted his life on spreading the word of the Lord. Scripted in a half-documentary, half-motion picture format, the film is narrative-driven, and is complemented by somber, moody music for some of the 'darker' scenes in the film concerning the abuses McDowell received in his early childhood. For some though, the film may seem preachy at times given its Christian message - but I personally thought it served more as a prelude or a backstory behind "More Than a Carpenter", a book he had written about the factual and historical basis behind the Christian faith.
(On a side note, the film also has excellent set design and features some rather authentic, vintage '50-60s automobiles and costumes)
