Code of Silence doesn't just roll the credits, but rather it leaves you thinking about betrayal, loyalty, and justice long after the show's over. The final episode wraps up Alison's journey from a quiet canteen worker to a brave insider who turns the tables on a ruthless gang.
Yes, Liam ends up behind bars, but not before making a powerful choice that changes both their lives. Want to know why he gave it all up, and how Alison came out stronger?
Here's a full breakdown of what went down in that last episode of Code of Silence.
Alison breaks the rules — and pays the price in the finale of Code of Silence
Everything in Code of Silence reaches a boiling point when Alison ignores orders and walks right into danger. Her undercover work was already shaky after Liam hacked her hearing aids and discovered she was working with the police. But when she figures out the gang's actual heist location isn't where she was told, she makes a fateful decision.

Instead of waiting for backup, she heads straight to the fancy hotel where Liam is busy retrieving a £5 million necklace. It's a tense moment - Braden's got a gun, shots are fired, and Detective Ben ends up wounded. Liam escapes with the jewels, Alison is shaken, and things spiral fast from there.
Love, lies, and a warehouse showdown
Back in hiding with her mum, Alison gets a suspicious food delivery - one with a burner phone hidden inside. The message? A familiar meeting spot. She sneaks away to find Liam waiting. Emotions fly as they argue about loyalty, guilt, and their shattered connection.
Liam wants them to run away to Brazil together. Alison refuses.
But their time apart doesn't last. Braden snatches Alison and sends Liam a chilling threat.

The only way to save her? Return the necklace. Liam does show up - with Helen in tow - and just when things seem bleak, the warehouse is stormed by police. It turns out Liam tipped them off.
The twist? He'd been planning revenge for years after the gang killed his foster father.
Truth revealed: Liam’s long game comes to light
The deeper twist in Code of Silence is Liam's real identity. His name isn't even Liam Barlow. He's Liam Grey, raised by a man murdered during one of Braden and Helen's previous jobs. Liam spent years gaining their trust, using his tech skills to infiltrate their network.
This whole time, Alison wasn't the only one playing a role. Liam was never just a love interest or a petty thief - he was out for justice. His moves weren't about money, but about taking down the people who hurt his family.

And when push came to shove, he chose to protect Alison over revenge. That one decision changed everything.
Alison walks away with her own win
Two months later, the dust has settled. Liam stands in court and pleads guilty. Alison is there, and the way she looks at him says it all - she understands why he did what he did. He signs a message inviting her to visit him. Whether she will or not remains open.
But Alison isn't left empty-handed. The police awarded her £50,000 for her help. More than that, she's found a new path - one that could lead to a future as a professional forensic lip reader.

For a woman who once blended into the background, Alison walks away with something far bigger than love or money - she's found her voice.
Code of Silence ends not with a cliché 'happily ever after', but with a quiet kind of power.
Alison doesn't run. Liam doesn't escape. But they both find closure in their way. It's a finale full of moral grey zones, emotional punches, and hard-earned growth.
And while the case might be closed, the door is left just slightly ajar for what could come next. Justice, after all, is rarely simple.
