The February 2020 Chicago Crossover Event is a two-part fictional crossover that exists within the Chicago television franchise. The event aired on NBC consecutively in two back-to-back one-hour timeslots on February 26, 2020. It began with "Off the Grid" of Chicago Fire and concluded with "Burden of Truth" of Chicago P.D. Both episodes followed a unified storyline of a former Chicago police officer returning to Chicago to search for his missing sister. Many actors in the franchise appeared outside of their main series guest starring in the other part of the crossover. The crossover event most notably featured the publicized return of former Chicago P.D. series regular Brian Geraghty who portrays Sean Roman and last appeared in the franchise in 2016.
