Tracing alien radio transmissions received in New York City, Loengard and Sayers suspect the Hive is planning an operation around the American debut of the Beatles on The Ed Sullivan Show. At the studio where preparations are underway, they find nothing suspicious. However, after learning the radio operator they're tracking died recently in a mysterious traffic accident, they find a second phone number for another suspect operator. Meanwhile, Bach stumbles onto evidence that the Hive has been rejecting some abductees.
