Watch Code 9 (BBC Worldwide)

Code 9 is a thrilling, high-stakes drama from BBC Worldwide that first aired in 2008. The show follows a team of three young people who are part of a top-secret government organization tasked with anticipating and preventing terrorist attacks. These "code breakers" use their expertise in technology and code-breaking to stay one step ahead of the terrorists and thwart their plans before they can cause harm.

The show is set in modern-day London, where the threat of terrorism is ever-present. The central characters are Lizzie, a computer hacker and expert in information technology; Will, a former soldier who brings tactical knowledge and combat training to the team; and Danny, a linguist who can decipher complex codes and communicate with foreign agents. Together, they form a tight-knit team whose skills complement each other's strengths and weaknesses.

Each episode of Code 9 takes on a different terrorist plot, presenting the code breakers with a new challenge to solve. These range from cyber-attacks on the city's infrastructure to coordinated bombings on crowded public spaces. The team works tirelessly to gather intelligence, analyze data, and decrypt codes to figure out the terrorists' plans and stop them before it's too late.

What sets Code 9 apart from other crime dramas is its emphasis on the technological side of anti-terrorism. Throughout the show, we see the code breakers using state-of-the-art equipment and software to track down leads and identify suspects. They also rely heavily on their knowledge of programming languages and code-breaking techniques -- skills that are rarely portrayed on television.

But Code 9 is not just a show about high-tech gadgets and savvy programming know-how. The characters are complex and relatable, with their own personal struggles and relationships to navigate. Lizzie, for instance, is deeply committed to her work but torn between her loyalty to the team and her desire for a normal life outside of work. Will, meanwhile, struggles with PTSD after his time in the military, and Danny is haunted by past decisions that put his colleagues in danger.

As the series progresses, the stakes only get higher, and the code breakers are put to the test in ever-more-difficult situations. We see them grapple with ethical dilemmas and difficult choices, as they fight to protect the city they love from those who wish to do it harm.

Overall, Code 9 is a gripping, fast-paced drama that will keep viewers on the edge of their seats. Its focus on technological espionage and code-breaking makes it stand out from other crime shows, while its complex characters and intricate plotlines ensure that it will keep viewers engaged from beginning to end.
