The three-hour event, dubbed “Imminent Threat,” is described as a high-stakes, global undertaking that will involve team members from
the FBI mothership and its International and Most Wanted offshoots. The crossover begins Tuesday, April 4 at 8/7c; as previously noted, the trio will air slightly out of its usual order that evening, with FBI: International kicking off the lineup instead of FBI proper.
Across three episodes — loglines for which can be found below — the series’ intrepid teams will work together when the abduction of an American citizen in Rome reveals an international plot to carry out a mass-casualty terror attack in New York City.
This marks CBS’ second crossover event for the three FBI series; the first one aired in September 2021 and served to launch the youngest offshoot, FBI: International. This does, however, mark the first global crossover event for FBI: Most Wanted‘s Dylan McDermott and Edwin Hodge, and FBI: International‘s Eva-Jane Willis, all of whom joined their casts over the past year.
