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, and he lives. 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!” Getting well and finding out who did this to him are the same job, and it is the only job Grant has. The trail runs from Siegfried's work to a scroll he discovers along the way, to a corrupt bureaucrat who has hijacked his identity, and finally back through his own family's history for how and why things turned out the way they did for them. One man, one line of enquiry, from the hospital bed to the name at the top.

Logline

Crushed in a car accident and left scooter-bound, Grant Davis is ambushed in his own home and injected with an engineered bioweapon, forcing a broken man to hunt the rogue agency that wants him dead before his body does.

Short synopsis

Grant Davis survives being crushed between two vehicles and wakes up in a Philadelphia collar, wrist splints, and a leg cast, getting around on a motorized scooter. Before he can recover, two men break into his home, beat him, and inject him with a genetically engineered pathogen built to evade the immune system entirely. What follows is a one-man investigation from hospital bed to courtroom to a scientist's lab in Germany, as Grant pieces together that he's a pawn in a turf war between rogue federal operators — and that the trail leads through a stolen identity, an old scroll, and his own family's buried history to the man who gave the order.

Extended synopsis
Grant Davis is folded like an accordion between two cars and, against odds, lives. He leaves the hospital not walking but scooting — collar braced, wrists splinted, leg in a cast from knee to toes — and starts the slow, humiliating work of getting his body back. That recovery becomes the least of his problems. Grant is unknowingly standing in the middle of a fight between rival federal factions that has already blown up in open court, where a judge holds two agents in contempt and has them dragged out. Break-ins start hitting his house. On the last one, two men force the door, drop him with a blow to the head, and hold him down while a needle goes into his arm. He hears one word before he blacks out: mycoplasma. What's in his bloodstream is Mycoplasma fermentans incognitus — a gain-of-function pathogen that mimics HIV's collapse of the immune system, but camouflages itself as the body's own cells so it's never flagged as an invader. Grant spends weeks sick, loses his job, and starts down two parallel tracks that turn out to be the same job: get well, and find out who did this and why. A collect call from Sing Sing — a hired inmate promising to kill him — becomes a black-comic standoff when Grant, calm and unbothered, tells the caller he's already dead and that every agency in the alphabet is now watching. It's the tonal signature of the whole piece: a broken man who refuses to be intimidated by people far more dangerous than he is. The investigation sends him to Dr. Siegfried, a zoologist-physicist in the German town of Tauberbischofsheim who may be the only person capable of reversing the damage. From there the trail widens — a scroll surfaces with information nobody was supposed to find, a bureaucrat is exposed as having hijacked Grant's identity for his own cover, and the low-level men who broke into his home start talking, revealing they were following orders from someone much further up a chain that goes all the way to a corrupt grey-division operation. The final turn pulls Grant's own family history into the frame, reframing the attack not as random but as the last move in a much older feud. Structurally, the story is a single-POV descent-and-reveal: one man, immobilized and furious, chasing one line of inquiry from a hospital bed to the name at the top. It's framed by its author as a true-events account, dictated rather than typed, which gives the material a raw, diaristic authenticity that a screen adaptation can lean into — a survivor's testimony re-weaponized as a thriller.
Why it adapts
The hook is the visual: a man fighting off armed operatives and chasing a global conspiracy while getting around on a motorized scooter, in a neck collar and steel wrist splints. That image alone is a poster and a trailer beat — an unlikely, wounded protagonist who cannot run, cannot fully defend himself, and refuses to stop anyway. The home-invasion sequence, the Sing Sing phone call ('Because I'm already dead'), and the courtroom contempt scene are all ready-made set pieces that don't need embellishment to play as tense, cinematic beats. The engineered-pathogen conceit gives the show a body-horror, ticking-clock engine that can be visualized (a virus that impersonates the body's own cells to hide from the immune system is inherently unsettling and translates well to procedural, microscope-level visuals intercut with the investigation). Layering in the German scientist, the scroll, the identity-theft bureaucrat, and the family-history reveal gives a writers' room multiple mid-season turns without inventing new IP — the real material already has the shape of a conspiracy box-set. The biggest asset for a producer is marketability: 'based on true events, dictated by a man who couldn't hold a pen while immobilized' is an authentic, differentiated hook for press and awards-season positioning, distinct from more fictionalized conspiracy thrillers. It gives a limited series a real-world anchor point similar to what fueled interest in Dopesick and Painkiller, while the scooter-bound-but-unstoppable protagonist gives marketing a singular, ownable image.
Format recommendation
Limited Series

The material spans a home-invasion thriller, a bioweapon conspiracy, a European scientist subplot, a hijacked-identity storyline, and a generational family-history reveal — that's five distinct engines that will feel compressed and rushed in a single feature. A 6-8 episode limited series gives each thread room to breathe and lets the central mystery (who gave the order, and why) unspool the way prestige conspiracy shows do, while still landing a contained, closed-ended story.

Comp titles
Painkiller (Netflix, 2023)
Same true-events-adjacent conspiracy engine — a wronged individual uncovering a much larger institutional cover-up, told with docudrama urgency.
Utopia (Amazon, 2020)
Shares the engineered-pathogen conspiracy hook and the paranoid, who-can-you-trust momentum of ordinary people up against a bioweapon plot.
The Report (2019)
Matches the tone of a lone investigator following a paper trail through federal misconduct to a name at the top, without relying on action-movie spectacle.
Reacher (Prime Video)
Comps the protagonist archetype — a physically compromised but unshakeable man who refuses to be intimidated by people who should terrify him.
Dopesick (Hulu, 2021)
Same 'inspired by true events' prestige-thriller register, mixing personal survival story with institutional corruption on a grand scale.
