Arthur Sterling, the supreme commander of "Aegis" the world's most powerful private military force and a hidden billionaire, returns home after completing a six-year top-secret mission. He expects to reunite with his wife and daughter, having sent massive monthly payments to his wife Sarah's account. But to his shock, Sarah had faked his death certificate, remarried a local wealthy bully named Marcus, and locked his six-year-old daughter Lily in a freezing basement dog cage, abusing her in every way. Enraged at the sight of his daughter's suffering, Arthur tears off his disguise and summons his elite old unit to descend upon the city. With devastating force, he crushes Marcus's empire, exposes Sarah's greed, and in a trail of fire and blood, builds an unshakable fortress of absolute protection for his daughter.
