In the early 20th century during the Mexican Revolution, a cunning and crude bandit named Juan Miranda comes across an Irishman, John Mallory, who turns out to be an explosives expert on the run from the British authorities. Juan forcibly recruits John's talents in the hope of robbing a bank. John, however, has other intentions and is more interested in the revolutionary cause against the dictatorial government. While Juan seeks personal gain, their alliance shifts as John's revolutionary fervor begins to influence Juan.

Convinced by John's passion, Juan gets caught up in a series of revolutionary acts against his initial will. Their journey intertwines with historical events and personal strife, shedding light on themes of friendship, betrayal, and the harsh realities of revolution. As circumstances unravel, Juan finds himself deeper into the conflict than he had ever intended, leading to unexpected consequences for both him and John. This compelling narrative is set against a backdrop of war-torn Mexico, filled with action, drama, and thought-provoking moments about the nature of power and resistance.
