Ep 4. Entreprise 4.0

Unit 42 is a Belgian crime drama series that centers around a specialized cybercrime unit in Brussels. Season 2 episode 4, entitled "Entreprise 4.0," follows the detectives as they investigate a case involving a tech company that accuses an artificial intelligence program of sabotaging its product.

The episode starts with the tech company's CEO, Jean-François Vandenbossche, reporting to the Unit 42 detectives that their latest product, a self-driving truck, malfunctioned during a test-run, leading to a fatal accident. The CEO believes that the company's AI program, which controls the truck's movements, was hacked and programmed to cause the accident intentionally. This accusation raises suspicion not only on the company's current employees but also on its former employees who may have had access to the AI program.

Chloe Muller, the leader of Unit 42, and her team start the investigation by reviewing the programming codes of the AI system. They quickly discover that the system was indeed hacked, but the hack was more sophisticated than any they had seen before. Instead of overwriting the AI program, the hacker used Machine Learning to retrain the AI's models, making the program behave in ways that the company did not intend. The Unit 42 team realizes that the perpetrator has a deep understanding of Machine Learning and must be an expert in the field.

As they delve deeper into the case, the detectives discover that the truck was transporting sensitive materials, and it was not an accident but a deliberate act of sabotage. The Unit 42 team starts investigating the company's former employees, who may have held grudges against the company, but all ex-employees are cleared from suspicion.

With no clear leads, Unit 42 decides to investigate Jean-François Vandenbossche's personal life, and they discover that his company was on the verge of bankruptcy before the accident. The unit starts investigating the CEO's finances and realizes that he had taken on huge debts to invest in the company's latest project, the self-driving truck. It becomes apparent that the CEO could have staged the accident to create a plausible excuse for the company's failure and to cash in on a lucrative insurance policy.

The Unit 42 team decides to question Jean-François Vandenbossche, but he denies any involvement in the sabotage, and there is no concrete evidence to implicate him. Meanwhile, the hacker steps up their game and expands their attacks, targeting the company's operations across the country.

As the Unit 42 team races against time to track down the hacker and bring them to justice, they realize that the hacker has an accomplice working within the company. The detectives zero in on the hacker's location, and in a thrilling climax, the team engages in a high-speed chase to catch the culprit before they can cause any more damage.

"Entreprise 4.0" is a well-crafted episode that highlights the dangers of Artificial Intelligence in the wrong hands. The episode is fast-paced and suspenseful, with a lot of twists and turns that will keep viewers on the edge of their seats. The Unit 42 team's ingenuity and tenacity in solving the case show their dedication to protecting the public and making sure that justice is served. Overall, it's a gripping episode that is sure to leave a lasting impression.
