海賊討伐

In 1135 at the Imperial Court, aristocrats are discussing countermeasures against pirates who are raising havoc in the Seto Inland Sea. Despite Tadazane's recommendation to place the Minamoto clan to expel the pirates, the retired Emperor Toba, who puts his trust in Tadamori, assigns the Taira clan to lead the punitive expedition. Tadamori, who wants to make Kiyomori his successor, orders Kiyomori to join the expedition, going against the opposition of Tadamasa. After arriving at the Sea, a giant vessel appears before Tadamori and Kiyomori.

１１３５年、朝廷では藤原忠実（國村隼）ら貴族たちが集まり瀬戸内海を荒らす海賊対策の会議に追われていた。通憲（阿部サダヲ）は自分のことしか考えぬ貴族たちにあきれ果てる。海賊討伐には源氏をと推挙する忠実を尻目に、鳥羽院（三上博史）は重用する忠盛（中井貴一）に海賊追討を命じる。初陣となった清盛（松山ケンイチ）は勇んで西海に出陣するが、清盛たち平氏軍の前に現れたのは見たこともないような巨大な海賊船だった。
