In the turbulent decade of the 1930s, during the Great Depression, the country is ravaged by crime. In this context, a famous bank robber and daring outlaw, John Dillinger, becomes the popular hero who challenges the authorities. With his irresistible charisma and bold style, Dillinger wins the public's admiration, becoming the FBI's Public Enemy Number One.
As Dillinger maneuvers between spectacular heists and impossible escapes, law enforcement agents, under the command of the tenacious agent Melvin Purvis, make plans to capture him. Purvis, determined to put Dillinger behind bars, hunts the criminal across the country, grappling with a system that often seems one step behind these charming delinquents. However, the manhunt becomes not only a professional obsession for Purvis but also a personal duel.

As Dillinger and Billie try to build a life together, the noose tightens. With moments of high tension, conflicting moral decisions, and the inevitable arrival of the law, the story explores the thin line between good and evil, attraction and repulsion, in a world where happiness is often overshadowed by betrayal and despair.
