NCIS uncovers a secret society of real-life super heroes and must track down the villain on tomorrow night's episode. The catalyst for that plot is the death of a Navy captain and the costume under his uniform.

The personal tie-in comes as DiNozzo is forced to work closely with his ex-fiancee, Wendy (Entourage's Perrey Reeves), during the course of the investigation. Will this former couple rekindle the romance?
