Captain Walker Keel, an old friend of Picard's, uses a top-secret frequency, thus excluding informing Riker, to summon him to a top-secret meeting with two other captain. The vague innuendo about a plot to take over a strategic sector of the Federation by replacing mysteriously dying Starfleet officers doesn't quite impress Picard, but he reconsiders after Keel and his crew die in an explosion. So he intends with Riker to visit Starfleet HQ, where he will dine with admirals and their aide Dexter Remmick, while Riker keeps an eye on admiral Aaron, who insists to visit the modernized Enterprise, actually carrying an alien brain-parasite.
