Whiteout (ホワイトアウト, Howaitoauto) is a 2000 Japanese film about a one-man fight against a terrorist attack at a dam in Japan, starring Yūji Oda (織田裕二) and Nanako Matsushima (松嶋菜々子).

It was an ordinary rescue mission for dam controller Togashi Teruo (Yūji Oda) and his colleague Yoshioka Kazushi as they set out to assist a few climbers who met an unexpected blizzard near the Okutowa Dam.

Things got worse when WHITEOUT - a meteorological phenomenon – appeared and Togashi lost his best friend forever.

Meanwhile, with the most advanced technology, Utsuki Hirotaka (Koichi Sato) and his group of terrorists blow up the only main road to Okutowa Dam, the largest dam in Japan.

Either the government pays the ransom or the dam will be blown up, spelling doom for the 200,000 residents living close to it.
