Fans of the "Law & Order" universe, get ready to have your minds blown. NBC has just announced that the cast of each spin-off – Law & Order, Special Victims Unit and Organized Crime – will come together for a three-hour special event, kicking off the new seasons of each criminal drama. Capt. Olivia Benson (Mariska Hargitay), Det. Elliot Stabler (Chris Meloni) and District Attorney Jack McCoy (Sam Waterston) will join forces on a single case that will unite all three of their units for one all-encompassing story. The Law & Order crossover premiere airs Thursday, Sept. 22 starting at 8 p.m. ET/PT on NBC. It will also be available to stream the next day on Peacock.
