Talk about a tough crowd!

On Wednesday's new episode of Chicago P.D. (10/9c, NBC), Antonio (Jon Seda) goes undercover with a dangerous robbery crew to find a missing narcotics officer. Although he already has an "in" with the group, Antonio gets punched in the face by their suspicious leader at their first meeting. Ouch! To prove himself trustworthy, Antonio also has to help in the heist of $3 million worth of unpackaged Oxycontin.
