The strongest superhero, Lucien, finally defeats his enemies and brings peace to the world. But upon returning home, he discovers that his mother has been humiliated and lost her house, while his daughter is being bullied at school. His long-missing wife has become the wife of the boss of the Corvus Corporation, who ignores both Lucien's mother and daughter. As Lucien investigates, he uncovers a powerful criminal network involved in the attacks on his family—including elements from within the government. Hiding his identity, Lucien tracks down the truth and eventually realizes that everything was orchestrated by the Corvus Corporation, whose leader turns out to be the very supervillain Lucien once defeated.
