The first season of Law & Order premiered on NBC on September 13, 1990, and concluded on June 9, 1991.

And it was also the first season to include Chris Noth as Junior Detective Mike Logan, Dann Florek as Captain Donald Cragen, Michael Moriarty as Executive Assistant District Attorney Ben Stone, Richard Brooks as Assistant District Attorney Paul Robinette and Steven Hill as District Attorney Adam Schiff.

Everybody's Favorite Bagman was produced in 1988 for CBS and was intended as the pilot episode of the series.

One future core cast member actress made her first appearance in the episode "Mushrooms".

Captain Cragen ends up in the cross-hairs of an internal investigation into evidence tampering, and the DA's office is forced to put him in a precarious situation to implicate the conspirators.
