Trailer - Summer Wars [English-subtitled]

Pia has posted the full trailer for Mamoru Hosoda’s Summer Wars, which will be released by Warner Bros. in Japan on August 1, 2009.

Plot: When timid eleventh-grader and math genius Kenji Koiso (Ryunosuke Kamiki) is asked by older student and secret crush Natsuki (Nanami Sakuraba) to come with her to her family’s Nagano home for a summer job, he agrees without hesitation. Natsuki’s family, the Jinnouchi clan, dates back to the Muromachi era (1336 to 1573), and they’ve all come together to celebrate the 90th birthday of the spunky matriarch of the family, Sakae. That’s when Kenji discovers his “summer job” is to pretend to be Natsuki’s fiance and dance with her at the birthday celebration. As Kenji attempts to keep up with Natsuki’s act around her family, he receives a strange math problem on his cell phone which, being a math genius, he can’t resist solving. As it turns out, the solution to the mysterious equation allows a malicious artificial intelligence to hack into a worldwide network called “OZ” and it’s up to Kenji and his new fake family to put reality back in order before the AI uses OZ’s many connections to vital real world systems to cause massive damage.
