The police procedural drama has earned a dedicated fan following over the years, featuring some intriguing cases as the international team of the FBI investigates crimes across Europe and brings criminals to justice.

In the previous episode, the agents had to carry out a prisoner swap, which turned into chaos as their entourage was attacked. In the next episode, the team will be on the lookout for a serial killer who has wreaked havoc in not just one country.
