Influenza is an easily understandable introduction to the ecology of the flu, its rate and factors of transmission, and the particular danger it represents for members of high-risk groups. Like a scientific road movie, it travels the world to consult the leading researchers trying to unlock the mysteries of this highly contagious disease. We also learn about the major epidemics that have swept the world, including the Spanish flu which claimed 20 million lives and the earliest discoveries of the virus that causes the disease. While explaining how the influenza virus outsmarts our immune system, the documentary emphasizes that there is still much we do not know about the constant evolution of the virus which enables it to remain always a step ahead of researchers.
