Lelouch died to save the world. This movie asks what happens when that sacrifice gets undone, and whether the person who comes back is still the same person his friends loved. The animation carries every quiet moment between the chaos, and every scene earns the weight it carries because you've already grieved him once. This isn't a resurrection story dressed up as fanservice. It's a reckoning with what peace costs when the architect of that peace returns to find his friends built something he might destroy just by existing again.

Years have passed since Lelouch sacrificed everything to bring peace to a fractured world. The United Federation of Nations now guides a fragile calm, and his friends work to preserve it. That calm breaks when militants abduct former princess Nunnally and Suzaku, who was escorting her while disguised as Zero, during a visit to a refugee camp. Suspicion falls on the Kingdom of Zilkhstan, a warrior nation that once beat back the Britannian army. Acting on secret orders from Schneizel, Kallen, Lloyd and Sayoko slip into the country, where a mysterious Geass user attacks them. There they also find the immortal witch C.C., who is working to bring Lelouch back to life. The film is a sci-fi mecha drama packed with action.
