Billion Dollar Brain

Harry Palmer (Michael Caine) is a former British secret agent who has taken up work as a private detective. An anonymous party hires him to deliver a seemingly normal package to Helsinki. However, he learns that he has been deceived into working for the Secret Service again, and is actually returning stolen virus-infected eggs to a government lab. Palmer is then persuaded to thwart a manic Texas oil baron (Ed Begley) who is planning to attack the Soviet Union with a supercomputer.
