Gibbs is ordered to meet with a convicted serial killer three days away from his execution in order to find out crucial information before he dies.

Under order from the Governor of Virginia, a skeptical Gibbs is forced to meet with a serial killer he helped to convict a decade before under the pretense that the killer will tell Gibbs where he hid missing bodies and give closure to the families before his death. Gibbs' instinct is correct when the killer is coy and doesn't reveal what he promised. Nonetheless, Gibbs has an NCIS team in place to re-investigate the possible locations of the victims. When a crucial piece of information is discovered, Abby and McGee use their expertise to attempt to pinpoint where the bodies might be.
