Fire insurance investigator Norman Foster exposes a crooked scheme from a powerful businessman Sidney Blackmer in this decent B drama with Evelyn Knapp as the niece of the villain who falls in love with the hero. She causes problems for him in the opening scene and ends up rescuing her dog who hitches a ride with him and ends up in a burning building. That fire is a small oven flame in comparison to the scary blaze that comes out of the fraud and entraps seemingly hundreds if workers in a warehouse. The screams of panic on these extras seems genuine which adds a ton of terror into the film's mood. That makes this truly a bail biting experience, rising it above the normal level of B melodrama.
