Inspired by the recent success of The Blue Lamp, I Believe in You is a multiplotted British drama about parole officers. Several short character vignettes pass our way as the film studies the various methods employed by the officers in dealing with their charges. The film settles upon Cecil Parker, a compassionate official who takes special interest in the parolees. Parker tries simultaneously to reform a hardened criminal, and to dissuade a budding juvenile delinquent from a life of perdition. The semi-documentary approach established early in I Believe in You gives way to sentiment as the film winds down.
