Muranishi (Takayuki Yamada), who stood at the apex of the adult film industry at the beginning of the Heisei period, has produced numerous planned series, but these fell far short of the legendary BDSM-esque works he made together with Kuroki (Misato Morita). Kuroki longs to work with Muranishi again but cannot, and slowly the two grow apart.
Then, Muranishi is encouraged to get into satellite broadcasting. Dreaming of “raining porn from the sky,” he begins to raise funds. Close companion Kawada (Tetsuji Tamayama) is concerned about Muranishi, but Muranishi does not listen and instead leaves, founds a new company, Diamond Visual, and begins promoting new actresses such as Mariko Nogi (Yuri Tsunematsu).
At the same time, his old friend Toshi (Shinnosuke Mitsushima), who joined a yakuza group led by Furuya (Jun Kunimura), has mixed feelings toward Muranishi.
