Grace's niece, Sayre, is arrested after attending a drug-laced scavenger party. The teens run into trouble after raiding their parents' medicine cabinets, then mixing different drugs. When the squad tries to figure out what combination landed Sayre's best friend in a coma, they discover that some of the drugs contained a potentially deadly substance. Grace's temporary partner, Abby (special guest star Christina Ricci), proves herself quite resourceful in getting good leads on the case. But she doesn't know everything, and Grace isn't about to let her forget that fact. Airing Monday March 9, 2009 on TNT.
