Things are looking great for Mark. He’s got his dream job, working alongside his newly promoted buddy AJ. They do everything together. Episode 1 finds the Khromacom gang at a Karaoke bar. As ever there are security situations everywhere: unsecured phones being left out in public; people writing their passwords down. What else do you expect when people are having fun?

Mark and AJ are called into the team on a new top-secret project, e.v.e. They get to meet technology biz guru, Justin, and the tech brains behind him, Dev. Mark is tasked with setting up security on the mystery project, but the first meeting for the team sees some cracks appearing in their confidentiality protocols.

Mark and Charlotte’s dinner date is an opportunity for Mark to impress. While he’s a ‘wiz’ at all things security, that clearly doesn’t extend to the kitchen. Meanwhile ‘Aunt Margret’ is turning up the heat and Charlotte finds herself engaged in a hack battle with a skilled adversary. The consequences of earlier phone security errors play out in this tense and funny battle of wits.

At last the wraps are lifted from the top-secret project. Mark, AJ and the rest of the team are introduced to e.v.e – a virtual assistant like nothing we’ve seen before. Mark voices his concern to Dev about the security implications of having connected tech that can ‘hear’ everything that’s said in the office. Then Mark receives a message that threatens to raise the ghost of his previous life.

The new attack by Charlotte has set off some virtual alarms and AJ is helping their colleague Dawn to protect herself from a spoofing attack, after her phone was compromised. Meanwhile, Mark’s old hacker life threatens to come crashing back when he finds himself at a ‘Wellness Centre’ set up by his old controller ‘Maurice’. Surely it can’t just be about re-aligning some ‘chakras’?

Charlotte steps up her social engineering activity, manipulating fellow employees through vishing and impersonation. She’s an impressive adversary and even the security team are not immune. Mark finds himself teaming up with an unlikely ally to try to combat her and her controller, the mysterious ‘Aunt Margret’.

Mark and Charlotte finally make it to dinner at a ‘hipster’ restaurant. Mark’s counter-attack begins, giving Charlotte a taste of her own medicine; using 3rd party apps on her phone. In the process Mark discovers Charlotte’s true motives for targeting Khromacom. The surprises just keep on coming and Mark finds his loyalties tested to the limit.

The launch of e.v.e is just days away and the team is pulled into an unscheduled planning meeting. Dev is relying on Mark and AJ to keep the system secure against a threat of which only Mark knows the true scale. Finally, we start to see the real scope of e.v.e‘s capabilities. Never before has the maxim ‘trust no-one’ seemed more relevant

e.v.e’s launch day minus one and Charlotte is showing herself to be as skilful an actor as she is hacker. Maurice is forced to cash in some old favours, no matter how far flung, or how deep ‘undercover’, to find out who’s really behind the growing web of conspiracy. Meanwhile AJ is having doubts about his friendship with Mark, who seems worryingly distracted and evasive. Not surprising really, after a game-changing revelation that no-one saw coming.

It’s the day of the big launch. The excitement and the threat levels around e.v.e are through the roof. AJ and Mark take the team through the critical security protocols. Meanwhile Charlotte impersonates her way into a bedroom at the launch event hotel. So at last we come to the final showdown. Mark is going to have to draw on all his powers of persuasion to save Charlotte, but time is running out.

Finally, all of the secrets are laid bare, all of the webs of deceit unravel. The revelations come thick and fast for Charlotte, AJ and Dev. By the end of this emotional and tense episode everything they thought they knew will be turned inside-out. Who will emerge on the side of truth? What will happen to all those treasured friendships and loyalties? In a stunning revelation the betrayer will be betrayed.

Mark and AJ face the aftermath. In the remains of the e.v.e launch they survey a world seemingly turned upside-down. So many questions are still unanswered. Can their friendship survive? Could someone really end up in jail? And maybe most important of all, where is Charlotte? All will be revealed and more in this intriguing and uplifting Season finale.
