The central plot of FBI: International doesn't appear to differ too much from FBI or FBI: Most Wanted. The FBI and the cases it takes on will still be the central focus. What the plot is aiming to do, however, is help expand the cases and actions of the FBI while also giving the spotlight to another division. Via TV Series Finale, CBS said that the plot of FBI International basically follows the top agents from the FBI's International Division as they travel the world while trying to protect Americans wherever they may be.
The plot opens the door for the series to explore a multitude of cases in many different countries. What's even more intriguing about FBI: International's plot is that its debut will result in a planned crossover with FBI and FBI: Most Wanted. This could mean that FBI and FBI: Most Wanted's cast is dealt with a case that is beyond their resources or reach and now have to rely on the bureau's International Division. It could serve as a great way to introduce the new spin-off while also expanding upon the central plot from the other two series.
