This is one of those white power films. Essentially the main character is sent on a mission to kill these Japanese people.
She then gets upset that someone from the side she has been killing has poisoned her with radiation. She then goes on a mission killing more japenese people in the hope that she finds the person calling the shots whiles sparing the white person who administers the posion.
She manages to kidnap a Japanese girl and threatens to kill her unless the top man shows himself to presumably be killed by Karen
Basically white Karen women gets upset and many Japanese people die.
