Special Agent Scott Forrester and his Budapest-based FBI fly team head to Croatia, after Isobel Castille enlists their help to capture an American fugitive who escaped to Zagreb with a 14-year-old girl. OA continues with the mission overseas, intent on bringing the fugitive to justice, while Europol agent Katrin Jaeger attempts to help the team secure the necessary support and access from the less-than-cooperative local authorities.
Tropes:
- Corrupt Politician: The Fly Team arrests Ukrainian Deputy Defense Minister Fedir Rusnak for trying to assist Kent in entering Ukraine because once he's there, the US government can't officially request Kiev to extradite Kent back.note
- Crossover: The third part of a triple crossover with the parent FBI series and fellow spin-off FBI: Most Wanted.
- Dirty Cop: Forrester accuses the Croatian cop who appears immediately to expel the FBI from Kuprevic's home of being this for the latter. However, it is never confirmed; the cop denies any knowledge of Kuprevic being a pedophile, and when presented with evidence, he has no problem arresting him.
- Earn Your Happy Ending: After what Colin Kent did to give the New York-based FBI agents a headache, the Hungarian Fly Team apprehends him with help from OA. His blackmail evidence was obtained and used to nail influential persons worldwide for pedophile activities. OA was also able to rescue Sunny and bring her back to the US.
- Human Traffickers: Colin Kent's organization is this. He is obviously based on Jeffrey Epstein.
- In My Language, That Sounds Like...: The Fly Team listens to Kent talking about meeting someone "in the Greek" on the phone. They later realize that he means the Grič, an anti-air gallery underground that was built in Zagreb during World War II.
- Jurisdiction Friction: The Fly Team is forced to leave Ivan Krupevic's mansion by Croatian police because they don't have any legal authority to be there, even though the team has suspicions that he's tight with Kent.
- Also, O.A. from the New York office (original FBI) joining the team to catch Colin Kent. Forrester believes this trope is at work and tries to get him out, but relents when O.A. says that he's there because It's Personal and doesn't want to direct or take over the investigation. They butt heads again when O.A. wants to arrest Kent on the first opportunity but Forrester wants him to provide evidence on other pedophiles first.
- Made a Slave: What Kent intends for Sunny, basically, as he 'sells' her for a contact with a politician who will give him shelter in a country with no extradition treaty with the U.S.
- New Meat: Cameron Vo joins the Fly Team after being transferred from Seattle.
- Run for the Border: Kent flies to Croatia from the U.S., to the FBI's surprise because Croatia has an extradition treaty with them. They later find that he's using it as a stopover before reaching Ukraine, which does not.
- Screw the Rules, I Have Money!: Kent invokes this when caught, claiming that he will use his fortune to fight extradition in the courts and muddle the waters further by suing Forrester's team. It falls flat and he's handed immediately to O.A. to take him back to America.
- Tunnel Network: Zagreb's Grič Tunnel.
- Wham Shot: The final scene has Forrester coming to his apartment to find second-in-command Kellett in bed, showing they're secretly in a relationship.
