The city anxiously anticipates the arrival of Heather Taffet, more notoriously known as "The Gravedigger," for her final appeal after being sentenced to death for a kidnap-murder and a series of similar coldblooded crimes. But when a bullet targeted at The Gravedigger is fired from a distance and hits her, the Jeffersonian team is tasked to piece together the sniper's precise location as well as identify the suspect and his motives. Meanwhile, Sweets attempts to put on a brave face after being caught in the firestorm just moments following a chilly encounter with The Gravedigger.

Remains are discovered on the roof of a warehouse after a failed bike stunt. Meanwhile, Sweets turns to Booth for advice about his relationship with Daisy, and Booth makes a decision about his relationship with Hannah.
