Stardate: 4129.5 Councilor Deanna Troi’s mother, Lwaxana, drops by for a surprise visit. Lwaxana has come to inform Deanna that the arranged marriage her father had set up for her while she was still a child, is about to occur. Although Deanna has known about the arrangement, she had just assumed the arrangement had been called off due to her career in Starfleet. Even though she has never met the groom, Deanna believes she has being seeing visions of him, so she agrees to acquiesce to this Betazoid tradition.

However, the wedding plans are thrown into chaos when a major plaque ship approaches and threatens a world. Enterprise responds to the planet’s distress call, but soon both Enterprise and Deanna find that not all is as it appears to be with the plague and her groom.
