Inspired by a true story, this action-adventure thriller concerns the race to obtain the blueprints of a MIG-25 "Foxbat" Soviet fighter plane which has landed in Japan, complete with a pilot who is asking for asylum. Undercover U.S. spy Michael Saxon (Henry Silva) is trying to get the microfilms for the state-of-the art film back to his country, but he is competing against agents and representatives from many countries for the privilege: at one point there is a super-secret auction of the plans. Naturally, the KGB is not taking this situation sitting down, and agents are dispatched to destroy the plans and anyone who has them. The action moves from Tokyo to Hong Kong, as Saxon attempts to contact a man who can arrange for the proper delivery of the plans.
