Plot

Joe Martin is a fire fighter in Los Angeles who is assigned to the Arson Detail. His first assignment is to investigate a suspicious fur store fire that seems to be set by the store owner himself, Thomas Peyson. Joe's predecessor in the Arson Detail was killed when investigating the same fire and his file with his findings wasn't recovered from his body. This is just one of many suspicious fires in the last few years, where the insurance claims have been filed by the same agent, Frederick P. Fender.
