The Five Families of the American Mafia, formed after a consolidation and the formation of the Commission in 1931, pushed the American Mafia to its peak. However, a new generation of leaders emerged, leading to a change within the Mafia, and the Gomorrah family from Italy began to unify the Mafia. They tore up the peace agreement, and a decade-long internal warfare began, leaving the American Mafia in chaos once again.

The protagonist, the heir of the Ferro family, was ambushed on his way home. With the family on the verge of splitting in the absence of leadership, the protagonist bravely took on the family's heavy responsibility and became the leader. He pledged to avenge his father's death and restore the family's glory. But, will the Five Families accept defeat, and what kind of conspiracy is brewing in the dark?
