Hanna and Jules are sent on their first mission - to kill a journalist in London planning to meet with a military lawyer intent on exposing Utrax’s secrets - whilst Sandy and Clara fly to Barcelona to recover the evidence. Hanna attempts to back out and joins forces with Mannion in an attempt to save Nicola’s life, but Jules and Leo are one step ahead. The consequences are disastrous.

Following Gelder’s murder, Carmichael arrives in Barcelona whilst Hanna, Clara and Kat hide in a hillside villa. Hanna returns to the hotel and recovers Gelder’s target list, helped out by Marissa, who follows Carmichael to the villa and blackmails him into bringing his fellow Utrax leaders to justice. Hanna allows Clara to reunite with her mother before returning to Marissa to help destroy Utrax.
