Blair Underwood

The action heats up on this week's Ironside, when the NBC drama's titular character (played by Blair Underwood) and his team try to track down a serial stabber.

As Virgil (Pablo Schreiber) and Teddy (Neal Bledsoe) are hot on the serial killer's trail, Det. Ironside and Holly (Spencer Grammer) investigate a case-within-a-case when they discover a teenage witness to the slashing went missing as a child. Their search takes them to the heart of the New York City's Greenwich Village where Ironside finds himself in the middle of a heated exchange.

Check out an exclusive clip below from Ironside, airing Wednesday at 10/9c on NBC.
