A pause in small boat crossings and a coincidence that reveals how boats are delivered.

A journalist and an ex-soldier search for the identity of a people smuggler believed to be responsible for thousands of illegal crossings to the UK by small boats and lorries.

They start with a false name: Kardo Ranya. A man who has evaded arrest for several years by keeping his real identity a closely guarded secret. It makes it near impossible for law enforcement agencies to issue and international arrest warrant.

Sue and Rob know what he looks like from social media posts advertising his crossings and lifestyle. Their search takes them across Europe and to the Middle East, where they discover a network of powerful smugglers operating from a town in Northern Iraq.

It’s two years since Sue and Rob located a gang leader in their podcast Intrigue: To Catch a Scorpion and the illegal business of migrant journeys is more dangerous and ruthless than before.

Their investigation reveals the inner mechanics of the smuggling trade and shows in close focus the people who currently control it as they search for a kingpin behind dangerous crossings to the UK by boat and lorry.

A secret meeting, a missing person and a worried family. Who is the man connecting them?

Within a month of the Vastaamo data breach, Tomi Haustola, a Finnish stand up comedian, is on stage making jokes about it.

But Tomi himself is one of the thousands of victims. He tells Jenny how he went to Vastaamo because he was burnt-out and anxious and couldn’t tell anyone - except his therapist.

When he discovers a hacker had stolen his therapy notes, Tomi decides to share his story with the audience. Many of them are victims themselves.

But he doesn’t expect a letter to arrive for him, years after the hack, inviting him to view the trial of Julius Kivimäki, the man authorities suspected of being the extortionist ransom_man.

Bringing the case against him is the Prosecutor Pasi Vainio.

Kivimäki is defended by the lawyer who has been with him since the beginning - Peter Jaari.

Also present is Jenni Raiskio, the lawyer representing victims of the hack, making sure they are not forgotten amidst the TV cameras and photographers.

As Jenny follows the unfolding of the court case and the trial nears its conclusion, something happens that puts everything in jeopardy.

Authorities think Julius Kivimäki could be responsible for the Vastaamo data breach and the leaking of patient records.

They want to bring him in for questioning, but he’s disappeared. Kivimäki is known to brag about his international lifestyle. He could be anywhere.

Jenny meets Pasi Vainio, the prosecutor who places Kivimäki on Europol’s Most Wanted List. Pasi takes Jenny through the evidence that he and his colleagues have painstakingly gathered, trying to figure out who is ransom_man.

What they find is shocking and surprising, and takes Jenny closer to home than she ever expected.

Through all of this, one man has stood by Kivimäki’s side - his lawyer, Peter Jaari. Jenny heads to Peter’s Helsinki office to see if he can provide any answers.

The search for Kivimäki leads to a confrontation that no one saw coming.

ransom_man’s final post contained clues to his identity. In those clues, former cybercrime detective Antti Kurittu recognises similarities to of the biggest hacker he ever investigated, a Finnish teenager called Julius Kivimäki.

So who is Julius Kivimäki, and could he be the person who held a nation’s darkest secrets to ransom?

Jenny’s search for answers leads her away from Finland, to meet a man in Illinois named Blair. Blair grew up in the hacking scene, and his time in the same circles as Kivimäki would shape his life forever.

Blair found himself at the centre of a vicious online feud that spilled into the real world. It began with an unexpected takeaway delivery and ultimately put his and his family’s life in danger.

Jenny explores how Julius Kivimäki became a globally notorious hacker - his name has been linked to grounding of a plane with a hoax bomb threat, the targeting of elite universities and multinational corporations, and perpetrating tens of thousands of hacks. But was Vastaamo among them?

A shocking data breach at a Finnish psychotherapy service. Jenny Kleeman traces the story of a nation’s secrets held to ransom by a faceless hacker. We all have some thoughts we’d never write down. Now, just imagine that someone had got hold of those thoughts, and was threatening to publish them for all the world to see - if you didn’t pay to stop them.

This is what happened to Tiina, a Headteacher living near Helsinki. When decades of stress and anxiety overwhelmed her, she sought support through a therapy service called Vastaamo.

Vastaamo was accessible, affordable, and a national success story. But in September 2020, the company received an email from a hacker claiming to have stolen their entire patient database - including therapy notes.

Antti Kurittu is the cybersecurity specialist tasked with saving the secrets of 33,000 patients, but can he and the police find a way to stop this hacker, who calls himself ransom_man?

Before long, Antti, Tiina and a whole nation learn just how far he is willing to go.
