This masculine film mainly depicts four boys who grew up together in the slums. They have different personalities, but they share the same ideal, hoping to become the leader of the underworld in the future. Lansky is a man of business and economic acumen; Benny is strong and impulsive; Luciano is so popular that he finally has a chance to root out the gang boss by taking advantage of his strengths; and Costello is well-versed in political careers and is good at manipulating his skills, so he becomes an outstanding politician. The film develops the plot around the growth process of the four of them, and the characters are delicately depicted.
