First part of the third season of the Shingeki no Kyojin. For centuries, humanity has been hunted by giant, mysterious predators known as the Titans. Three mighty walls—Wall Maria, Rose, and Sheena—provided peace and protection for humanity for over a hundred years. That peace, however, was shattered when the Colossus Titan and Armored Titan appeared and destroyed the outermost wall, Wall Maria. Forced to retreat behind Wall Rose, humanity waited with bated breath for the Titans to reappear and destroy their safe haven once more.
