NCIS picks up tonight where last week's "Playing With Fire" left off (see review and Round Table for a full discussion of that episode). Hot on the trail of the Navy arsonist, the team makes an alarming discovery.

When Abby analyzes the high-tech bug found inside the probationary agent’s tooth, NCIS is left searching for answers regarding how it got there. Gibbs, as always, is one step ahead of the rest.
