Grace investigates the vanishing of a troubled young man who shares a past tragedy with her: His father---like Grace's sister---was killed in the bombing of the Alfred P. Murrah Federal Building in Oklahoma City. Meanwhile, Ham separates from his wife, which only affords him more time for sex-tracurricular activities with Grace.

When a mother of two vanishes, clues point to a teen girl and her druggie boyfriend as suspects. Elsewhere, Grace's young nephew joins a police program and corners Ham about his romantic dalliances with Grace; and Butch is hounded by a possible stalker who is connected to the department.
