The team is on the case when human remains are found inside a barrel of wine during a wine tasting. When the victim turns out to be a wine critic whose scathing reviews were capable of sending a vineyard to its ruin, everyone from the winery's owner to the victim's own wife becomes a suspect.

Dismembered remains are discovered in several mailing boxes at a dead letter office, and the Jeffersonian team identifies the victim as an employee of a local Ship 'n' Print, where the staff recently split the winnings of a lottery prize. The team uncovers a complicated love triangle between two married employees and the victim, and while motive points to the husband a critical clue leads them to solve the crime definitively.
