In the summer of 1976, 36 bombs were detonated in Cleveland. At that time, Irish gangster Danny Glynn was in full swing in a turf war with Italian gangs. The film is based on a true story. It describes how Glynn rose from the mixed city of Cleveland to become the local gang law enforcer. He successfully escaped countless assassination attempts and fought back brutally, eliminating those who tried to assassinate him one by one. His ferocity and invincibility eventually led to the collapse of gangs across the United States. And he won the reputation of being an unkillable target for gangs. The story is about a gang fight in Cleveland, USA in the summer of 1976, with a total of 36 explosions, which eventually led to the collapse of American gangs and a major reshuffle of the American police. It was an unprecedented gang fight. The center of the incident was an Irish gang leader, who even threatened on TV: Whoever doesn't let him live, he won't let anyone live. So a large group of gangsters targeted the Irishman and launched a crazy attack, but they tried every possible means to get rid of him, and instead the Irishman retaliated wildly.
