Watch Babylon

At the suicide summit, Itsuki asks Alex to talk to a girl contemplating suicide. Alex, lost deep in thought in search of the truth behind good and evil, agrees to talk to the girl. On the other hand, Seizaki regards Itsuki's invitation with suspicion and holds tightly on to his gun. Meanwhile, Magase closes in quietly and surely on the two men as the world watches on.

The beginning of the G7 summit has arrived. The leaders of the seven countries, which now contain cities that have adopted the suicide law, gather together and share their stances on the suicide law. While the leaders debate the issue from the perspective of morality, economics, and rights, Alex poses a single question that cuts to the heart of the debate.

Seizaki and Hardy listen to the recording of the telephone call with Flores in a hospice. Meanwhile, Seizaki receives a report saying that Germany and Italy have also adopted the suicide law. In the midst of the confusion, something unbelievable happens right in front of their eyes.

The city of Hartford becomes the first city in the U.S. to declare their adoption of the suicide law. The White House holds an emergency meeting over the issue, and Alex calls Flores, the mayor. The suicide law had slowly begun to spread throughout the world ever since it was first announced in Shiniki.

After the parliamentary election, Shiniki was preparing to enact the suicide law. After his kidnap attempt on Itsuki, Seizaki is put under house arrest and spends his days overcome with a sense of powerlessness. One day, Seizaki is paid a visit by an important individual.

With their suspension lifted the ARV boys return to duty. But when footage goes viral of Banjo (Andrew Brooke) venting his frustrations on a rubbish bin and Sharon Franklin (Nicola Walker) proposes to reopen the nightclub shooting investigation, it sparks industrial action by TSG and firearms units. As civil unrest erupts on London's barely policed streets, Charles Inglis (Paterson Joseph) and Franklin go head to head to prove themselves the best choice for the job of Commissioner. And when potentially explosive material lands on Liz's (Brit Marling) desk she must decide whether to play king or queen-maker to salvage her vision of transparency and openness...

With tension in the capital rising in the aftermath of the nightclub shooting, Banjo (Andrew Brooke) reassures a nervous Robbie (Adam Deacon) ahead of the internal police investigation. At headquarters there's a vacancy at the top of the force and, in the eyes of Deputy Mayor Grant Delgado (Ralph Brown), Acting Commissioner Charles Inglis (Paterson Joseph) is already proving a more malleable candidate than his predecessor. With Finn (Bertie Carvel) as his most trusted advisor, Inglis' appointment would mean Liz (Brit Marling) is finished in the organisation. But when the hunt for a missing child proves fruitless Liz is inspired to find help in the unlikeliest of places and in the process may just have found a contender to challenge Inglis' bid for power....

More shocking detail emerges around Commissioner Miller's death and Liz is incriminated over the nature of her relationship with him. Finn concentrates his efforts on positioning himself as Acting Commissioner Inglis'consigliere and sidelining Liz in her own department. While police on the streets can only speculate about the extraordinary events higher up the food chain, the fugitive bomber is located.

It's Robbie's (Adam Deacon) first day on the ARV unit and with Warwick (Nick Blood) clearly not fit for duty he discovers how far Banjo (Andrew Brooke) and Tony (Stuart Martin) will bend the rules to help their brother in arms. Liz (Brit Marling) faces a backlash when the police play down a bomb threat at a conference centre but news goes viral and threatens to cause widespread panic. Deputy Commissioner Charles Inglis (Paterson Joseph) finds that nobody is above the law when his arrest over a minor offence heaps further pressure on Richard Miller (James Nesbitt). And as Liz accompanies Miller to diffuse media tension at the bomb scene he confides in her that a journalist has a story ready to run that is infinitely more explosive for the force and its chief...

Eager to justify Commissioner Miller's (James Nesbitt) faith in her, Liz (Brit Marling) presents her vision for Metwork: the force's very own digital news channel that will rival established outlets and tell it like it is, for better or worse. It could be a game-changer but to Finn (Bertie Carvel) Metwork is a vanity project and he is determined to kill it. His opportunity comes on the eve of the Mayor's Conference on Policing. With another clash with Deputy Mayor Grant Delgado (Ralph Brown) on the cards, a youth arrested for possession of drugs turns out to be Delgado's son. Finn leaks the news to trump Liz's big idea and ruin Delgado in the process. An indignant Liz (Brit Marling) helps Delgado save face unaware that she has rescued Miller's most powerful enemy. Warwick's psychological state reaches crisis point after the high-risk pursuit of a gang of armed robbers and firearms trainee Robbie (Adam Deacon) realises he must sharpen up if he is to make the cut....

A private security firm calls the police for assistance at a prison riot giving Liz Garvey the ideal opportunity to publicize the force's opposition to the transfer of essential services away from the public sector. But when her PR strategy backfires, tensions between the police and pro-privatisation City Hall boil over and Commissioner Miller finds himself under attack by Deputy Mayor Grant Delgado.

London's police is in need of an image makeover and Commissioner Richard Miller (James Nesbitt) has found just the woman to do it. A star of new media with a TED talk under her belt, ex-Instagram PR exec Liz Garvey (Brit Marling) has the vision and determination to shake things up in the largest and oldest police force in the world.
