It is 17th century Japan and Kamui is a fugitive Ninja on the run. He despises the lethal laws of the Ninja where he must use his skills to kill others, and is in search for true freedom. However, he is now hunted by his fellow ninjas as they must eliminate him for his betrayal. In order to live, he must constantly fight for his life and distrust others. An incident brings him to a fisherman's family, where he finally starts to open up to other people. Meanwhile, those hunting him are setting their trap. Kamui is a 2009 live-action movie directed by Yoichi Sai. It is based on a manga series by Sanpei Shirato from the '60s and '80s in which a fugitive ninja escapes his clan only to be hunted relentlessly by former colleagues who now consider him a worthless traitor.
