Finch Goes Undercover in Person of Interest’s “Last Call” (Images & Scoop)

Finch is headed undercover again in Person of Interest’s Feb. 18 episode.

“Last Call” sees Finch (Michael Emerson) assuming the role of a 911 emergency operator in order to protect another operator working at the center.

However, says CBS, it soon becomes clear that the threat reaches further than the team could have anticipated, leaving Harold with an emergency of his own.

Person of Interest stars Jim Caviezel (Reese), Michael Emerson (Finch), Kevin Chapman (Detective Fusco), Sarah Shahi (Shaw) and Amy Acker (Root).
