Gibbs and his remaining team members must head back to work with the past still weighing heavily on their minds.

In the conclusion of this two-part episode, after determining the serial killer's identity -- and some of his likely future targets -- the team and the FBI work together to apprehend him while trying to locate and protect the people he's preparing to kill.

In the season premiere episode, Seg-El is stranded far from home where his grandfather Val-El (series star IAN McELHINNEY) leads a rebellion against General Zod (COLIN SALMON).

The team searches for an interracial couple's six-year-old son, who was kidnapped from a farmer's market as his mother briefly looked away to make a purchase. The investigators wonder if the boy's estranged, wealthy, white-supremacist paternal grandfather, Joseph Pratt (Golden Globe Award nominee CHAD EVERETT - "Medical Center"), could be connected to the abduction. Series star ERIC CLOSE made his directorial debut with this episode.
