The Spikes Gang (1974)

Three boys wanted to be like their hero, Harry Spikes. They got their wish. Soon they were worth a fortune. DEAD or ALIVE.

Three teenage farm boys stumble upon Harry Spikes, a local bandit wounded in a gun battle. While Harry is recuperating, he regales the young men with stories of his exciting past. The adventurous tales inspire them to start a gang of their own. Failing at their first attempt to rob a bank, the boys convince the gruff Spikes to teach them the ways of the desperado.
