Criminal defense attorney Don Malarcik first encounters the technology when it’s used to implicate his young client in a murder.

In the ‘parallel universe’ of Boulder Colorado, defense attorney Eric Zale is working on a very similar case. A report claims to link a suspect to incriminating online activity, but offers no clear explanation of how it works or how its conclusions were reached. Unaware of Zale or any other Cybercheck cases outside of Akron, Don Malarcik continues to dig deeper. Don hires experts and investigators, but no one can verify Cyber Check’s methods or it’s creator Adam Mosher’s credentials. Meanwhile, prosecutors continue relying on the technology, presenting it as powerful, cutting-edge evidence. As Don prepares to challenge Mosher in court, he realizes he’s not just defending one client—he’s confronting a black-box system that could quietly reshape how guilt is determined, without transparency or accountability.

As Don connects with Colorado defense attorney Eric Zale, they compare notes and troubling inconsistencies emerge—Adam Mosher’s claims about his experience, expertise, and courtroom testimony don’t hold up under scrutiny. Investigators discover that key cases Mosher cited either never went to trial or never involved him at all, leading prosecutors in Colorado to drop charges rather than rely on his evidence. But in Akron, Cybercheck remains in use, and Mosher continues testifying under oath despite mounting doubts. Determined to stop what he believes is a dangerous and unverified system, Don launches a broader effort, reaching out to other defense attorneys and building a coalition to expose the truth—knowing the outcome could affect not just his clients, but the future of criminal justice itself.

Don Malarcik might finally uncover how Cybercheck works, as its creator Adam Mosher travels to Ohio to demonstrate the software to Don’s legal team and independent experts. While parts of the program appear functional, its core AI remains hidden, and Mosher refuses to provide full access or explain how it reaches conclusions that place suspects at crime scenes. His answers raise concerns about bias, and when he claims Cybercheck was peer-reviewed by a Canadian university, Don discovers the university denies any involvement. Believing this proves Mosher misled the court, Don prepares for a decisive hearing that could determine whether Cybercheck is legitimate evidence—or junk science.
