Captain Marvel and the Good Humor Man #1

Captain Marvel pursues the criminal Looter Luke and his gang after they steal a Good Humor ice cream truck during a movie shoot at a film studio. The villains use a smudge pot from the set to create a smoke screen and escape with the stolen money, prompting Captain Marvel to chase them down. The Captain Marvel Club Boys assist Captain Marvel in the effort to catch the crooks, with Director Lloyd Bacon instructing them to help capture the gang when he signals the "Niatpac Levram" alarm.
