'Law & Order: SVU': Watch Dann Florek's Dramatic Return (Exclusive Video)

Benson and Amaro need help on a case that harkens back to his days at the 27th Precinct, and on the original 'Law & Order.'

Capt. Cragen (Dann Florek) is coming home.

Law & Order: SVU's former boss returns on Wednesday's new episode, and his time away from the especially heinous and vicious felonies assigned to the SVU team seem to have done wonders for him.

However, he's not afraid to answer the call of duty on behalf of his former squad. In The Hollywood Reporter's exclusive sneak peek, Benson (Mariska Hargitay) and Amaro (Danny Pino) turn to Cragen for advice on an old case connected to the 27th Precinct – the longtime home base for the original Law & Order and Cragen's old stomping grounds before he moved to SVU.

Although no familiar names from the mothership series come up, there are a few other characters that Cragen is very familiar with.

Take a look at the clip from “Perverted Justice” below.

Law & Order: SVU airs Wednesdays at 9 p.m. on NBC.
