When bats crash into a high-rise building, scientists try to determine what interfered with their sonar, as it could be a threat to the nation's ability to detect enemy attacks on radar.
As with some other early episodes of the series, this one's more science than fiction, but does offer a worthwhile concept, kicking off a mystery to be solved. It's very logical in its investigations as the scientists go through their paces trying to find the answer, and the climax is just as logical, but a departure into more fantastic territory would have been more fun in my opinion.
