Dr. Bashir is assigned "babysitting" duty for four visiting ambassadors, O'Brien deals with an alien computer program downloaded from a probe, and Odo copes with a deeply infatuated Lwaxana Troi.

Deep Space Nine is host to a delegation of Federation ambassadors and Sisko gives Bashir the "honor" of welcoming them to the station. While Bashir struggles to please the other three dignitaries, Ambassador Lwaxana Troi exclaims that someone has stolen her latinum hair brooch. Although telepathic, she cannot sense guilt from anyone, and points out that Betazoids are unable to read Ferengi minds. Odo deduces that she might be unable to read Dopterians, distant cousins of the Ferengi, and arrests the man who stole her brooch. Lwaxana is instantly infatuated with the Constable.

Lwaxana visits the Security Office and flirts with Odo, who has obviously never been in such a situation. He nervously pretends someone is calling him on the Comm, but she is undeterred. Meanwhile, a mysterious probe-like vessel comes through the Wormhole and the rest of the crew attempt to interface with it. In Sisko's office, Odo asks for advice on how to deal with Lwaxana's aggressive behavior. Explaining he does not have time for "romantic interludes," Odo asks Sisko to do something about Lwaxana, to the Commander's amusement.

As Dax and O'Brien investigate the probe further, Lwaxana approaches Odo about having a picnic and is even more determined to catch his interest; when he informs her that he reverts to a liquid every sixteen hours, she shrugs and responds, "I can swim!" She follows Odo on his way to one of the station's Upper Pylons, but a system failure strands them together in a turbolift. "Alone at last!" Lwaxana declares gleefully.
