Bird flu is currently the center of all attention. Forty-one year old Nahoko Shindo is member of a group directly involved in the research for a solution that would put an end to the spread of the virus. She is a World Health Organization (WHO) doctor. Today, the greatest challenge for her and her colleagues is to prevent a global pandemic. To this end, the team takes various measures to contain the infection, such as identifying transmission routes and installing isolation wards. Meanwhile, at home, Shindo is a mother of two. Although she manages to balance work and family life, she flies off to other ends of the world as soon as there is news of a bird flu outbreak.
