Dynamite is a 1949 effort from the Pine-Thomas production mill. William Gargan and Richard Crane star as Gunner and Johnny, troubleshooters for dynamite contractor Hard Rock Mason Frank Ferguson. Though forced to work as a team on the job, Gunner and Johnny fall out when romance enters the picture in the form of Mason's pretty daughter Mary Virginia Welles. However, all misunderstandings are swept aside, however, when one of the men is trapped in a tunnel where several tons of TNT are about to go off.
