Synopsis

A motion picture feature, based on true events. A mystery thriller with suspense, translated into more than 40+ languages, listed with Publishers Weekly, a 30x #1 bestseller covered by USA Today, NY Weekly, LA Weekly and Entrepreneur Magazine, with the feature screenplay already written. NY Weekly wrote that it "emerged from the wreckage of trauma to become a story that continues to captivate and inspire - more than a bestseller, it's a testament to resilience." LA Weekly called it "a well-blended cosmopolitan cocktail of danger and delight." In the author's own words: this isn't just a thriller, it's a man's real-life descent into hell and fight for redemption. There is one diary and this novel is it, dictated to a computer by a man who could not hold a pen, told on a linear timeline. Grant Davis is based on the author, P.E. Barrington, who dictated every word of it while immobilized in a Philadelphia collar, steel wrist splints and a leg cast. Grant Davis is a passenger crushed between two vehicles, folded like an accordion, he was left with the kind of clarity only trauma can deliver. He wakes in a Philadelphia collar, steel splints on both wrists, a cast from his right knee to his toes, herniated discs up and down his neck and back, and concussion syndrome. He leaves the hospital on a motorized scooter, which is how he gets around from then on, and sets out to get his health back. He is not simply an accident victim. Grant stands between two rival forces whose fight has already reached a federal courtroom, where the judge holds two federal agents in contempt for ten thousand dollars and has them escorted out. What follows is a string of break-ins at Grant's home, reported to him by neighbors. On the last one, two men force the door. One strikes Grant in the head with a flapjack. His partner holds him down and puts a needle in his arm. One word from that night stays with him: mycoplasma. What he was injected with is Mycoplasma fermentans incognitus, genetically engineered and working entirely through gain-of-function. It behaves almost identically to HIV, with one difference: it morphs itself into an immune cell, or into anything that does not look like an invader, so the immune system passes it by. Hence incognitus. Grant is sick for weeks. His immune system weakens. He takes leave from his job. The two men who came through the door are henchmen for the higher-up who gave the order, working inside a corrupt grey division gone rogue. The apology comes later and from other men entirely: low-level minions already in trouble with the law, hoping to shorten their terms. It was out of their hands, they said. The order came from above. A friend tells Grant about Dr. Siegfried, a zoologist and physicist, and the only man who says he might be able to make him well. Grant travels to the historic German town of Tauberbischofsheim to find him. Then the phone rings and it's a collect call from Sing Sing from an inmate with a message: “I’m going to kill you, and you won’t see it coming!” Grant replied “Obviously your employer didn’t educate you on your subject. Two things you should know: There are a handful of alphabet agencies that have been keeping tabs on me for a very long time. In fact every phone has been monitored for decades. Even as we speak, this phone call has been triangulated and all of your information as well as all of your associate’s info are being examined, right now, in real time. Your entire existence is going to be under a zoom microscope from now on, so, get ready for a shit show! By the way, you can’t kill me.” He asked “Why is that?” Grant replied… “Because… I’m already dead!” A finalized screenplay adaptation, its 96 pages in industry format, WGA-registered along with U.S. Copyright. Available upon request to qualified producers, executives and literary agencies."

Logline

Crushed in a car accident and left scooter-bound, Grant Davis is ambushed in his own home and injected with an engineered pathogen — now he must expose the rogue federal faction hunting him before the disease finishes the job.

Short synopsis

After a catastrophic accident leaves him in a neck brace, wrist splints, and a leg cast, Grant Davis gets around on a motorized scooter while trying to rebuild his health. But he's already caught between rival factions inside a federal agency whose infighting has reached a judge's contempt order. Break-ins escalate until two men force their way into his home, beat him, and inject him with a genetically engineered organism designed to mimic HIV while evading detection. Sick, weakened, and abandoned by the system meant to protect him, Grant tracks the order up the chain — through low-level operators looking to save themselves, to a scientist in Germany who might cure him, and finally to a threat delivered from a prison payphone.

Extended synopsis
Grant Davis survives being crushed between two vehicles, waking up in a Philadelphia collar with steel wrist splints, a leg cast from knee to toe, herniated discs, and concussion syndrome. He leaves the hospital on a motorized scooter — his new, unglamorous mode of survival — determined to recover. But his physical trauma is only the opening wound. Grant is already entangled with a fractured federal agency: a courtroom scene shows a judge holding two agents in contempt and having them removed, evidence of a rot that has moved from paperwork to the street. That rot arrives at Grant's front door. After a string of reported break-ins, two men force their way in during his most vulnerable stretch of recovery — one strikes him with a flapjack, the other pins him down and injects him with Mycoplasma fermentans incognitus, a genetically engineered pathogen that mimics HIV but camouflages itself from the immune system entirely. Grant spends weeks sick, weakened, and forced off work, hunting for who gave the order and why he was chosen as the target. The men who broke in are muscle for a corrupt, off-book division operating without oversight. Apologies eventually come, but only from minor players trying to cut deals — men who insist the order came from someone above them. Grant's search for treatment leads him to Dr. Siegfried, a zoologist-physicist in the German town of Tauberbischofsheim who may be the only person capable of reversing what was done to him. The stakes sharpen when Grant receives a collect call from an inmate at Sing Sing threatening his life. Grant's icy, quotable reply — capped by the line 'Because... I'm already dead!' — signals a man who has stopped playing defense. The back half of the story follows Grant closing in on the man who gave the order, using the same paranoid clarity that trauma gave him in the wreckage to finally get answers. The book is framed as a firsthand account, dictated by the author while immobilized, giving the material an unusually specific, confessional voice — an ordinary, injured man forced into a fight against forces built to be untraceable.
Why it adapts
The core image sells itself on a poster: a man on a motorized scooter, physically broken, going up against an invisible federal-level conspiracy. That visual mismatch — fragility versus institutional menace — is a distinctive, marketable hook that doesn't require a franchise or IP recognition to explain in one image. The home-invasion injection scene is a built-in centerpiece setpiece, and the courtroom contempt sequence gives the conspiracy an early, concrete visual anchor instead of staying abstract. Grant himself is the asset: a wronged, physically compromised protagonist forced to out-think men who expect him to be an easy target, capped by a genuinely quotable, screen-ready exchange ('Because... I'm already dead!') that plays as a trailer moment. The Germany location (Tauberbischofsheim) and the eccentric zoologist-physicist character add texture and a change of setting that breaks up what could otherwise be a single-location thriller. Producers should go in clear-eyed: the source is a first-person dictated account with heavy self-promotional framing and an author-written screenplay already in hand, so any real adaptation will need an independent writer to convert diary reflection into dramatized scenes, sharpen the antagonist into a visible on-screen presence, and tighten the investigation into a propulsive three-act structure rather than a recovery memoir with thriller elements bolted on.
Format recommendation
Feature Film

The story tracks a single protagonist's linear arc — injury, attack, investigation, confrontation — which is classic contained-feature shape rather than a multi-season engine. That said, the source material is dictation-heavy and interior (a recovering man's diary), so the adaptation will need real invention to externalize the conspiracy into scenes, setpieces, and a visual antagonist rather than relying on narration.
