Several agents and innocent bystanders find themselves at the mercy of a talking briefcase, which barks out orders to deliver it to such-and-such an address, lest it explode and kill its bearer. It turns out that the briefcase contains secret documents, to be delivered to the other side's "Mr. Big." Imagine Steed and Tara's surprise when the briefcase orders them to deliver it to their own boss! Written by Terry Nation, "Take Me to Your Leader" premiered in England on March 5, 1969; it was previously seen in America on February 10 of that same year.
