Chicago Justice's first season kicked off with a three-show crossover, and it's ending with a crossover as well.

Sunday's season finale of the Dick Wolf legal procedural will welcome Chicago Fire star Eamonn Walker and Chicago P.D. star Sophia Bush. The Hollywood Reporter has an exclusive video of Bush's appearance.

The episode, titled "Tycoon," centers on the investigation into a crane collapse on a construction site that kills the son-in-law of wealthy real estate developer Frank Linden (The West Wing's Richard Schiff). With help from Chief Boden (Walker), Nagel (Joelle Carter) and Antonio (Jon Seda) discover that the collapse wasn't an accident. The team takes a hard look at Linden, who has made many enemies and dangerous friends, and is accustomed to using his wealth to get his way. 

The exclusive video marks a reunion for former Chicago P.D. co-stars Bush and Seda. Seda made the leap from P.D. to Justice almost halfway through P.D.'s current fourth season.

The crossovers come as Justice awaits word on a second season pickup. Chicago Fire, P.D. and Med were all renewed Wednesday.

Chicago Justice airs Sundays at 9 p.m. on NBC.
