Tom Mix Western #27

Tom Mix uncovers a plot to contaminate the town's water supply from a new dam and must stop the villains before they can destroy it and become heroes themselves. When Tom discovers that the real Professor Bimpkins has gone to the bank, he disguises himself to meet with the imposter and uncover the scheme. Tom then learns that criminals plan to use dynamite to blow up the dam's center, and he races to stop them by destroying their slow-burning fuse before the explosion can occur. In a climactic confrontation, Tom captures the gang of thieves who had orchestrated the plot, thwarting their plan to become celebrated as heroes by "accidentally" solving the water contamination crisis.
