For brothers Ryu and Chuzo Sakai of Japan, an inviteonly,
prestigious karate tournament was to be the
major final accomplishment capping their martial
arts careers. Little did they suspect the tournament
harbored a sinister element ensnaring the brothers
into a hidden, extraordinary, and dangerous world.
Chuzo will become an unwilling agent for a criminal
organization's ambitious plan for global supremacy,
while Ryu, with the help of American and Japanese
intelligence operatives, will be called to put his skill and
expertise into service to not only save Chuzo, but to
thwart the organization's operation to destabilize the
world order.
