An Irish detective stumbles upon some valuables that might be connected to a terrorist plot.
Darren Reid"s killers escape. Christian tells Emer another bomb is expected. In Antwerp, billionaire Richard Melnick shows the site for his new European headquarters to his son James, Bibi"s husband. Soon the CAB team link drug dealer Reid to Fionn Brannigan—Bibi"s brother. She tells Christian she left Ireland because of her brother"s dodgy dealings. It emerges that Reid"s last call was to Fionn.
Rough diamonds are found in Fionn's offices; Emer links this evidence to the bombings and warns Fionn that his life is in danger; Christian discovers that one of Sana's friends has been beaten by a fellow officer.
As the search for Fionn begins, Christian suggests that Fionn's frequent travels to Surat, India, may point to a diamond connection.
While Christian"s team searches for the bomber, CAB looks for a money trail linking Bibi to Fionn"s diamond-laundering scheme. Bibi offers Fionn"s wife a payoff, but she wants more money in exchange for Fionn"s hard drive. Sana"s friend Kamal turns up at the station with information about the night Sana disappeared, giving Christian and Emer a crucial lead.
Now in custody, Bibi admits to financial crimes and aiding the bombers, but under Belgian law she will only be charged with money laundering if she helps prevent the next bombing. Emer and Christian face a desperate race to stop the bomber and uncover who was really behind the terrorist campaign-and why.
