As New York City taxi driver Jerry Fletcher engages in conversations with Alice Sutton, a determined lawyer working at the U.S. Justice Department, it becomes increasingly clear that his quirky demeanor masks a profound paranoia. Driven by an obsession with conspiracy theories, Jerry is particularly drawn to Alice’s quest to unveil the truth surrounding her father’s enigmatic murder. Little does Alice know that Jerry has been stealthily tracking her every move, setting up a complex dynamic that separates him from the ordinary New Yorkers.

Jerry’s knack for surveillance ensnares him in a web of intrigue when he mistakenly identifies a group of men as CIA agents. When he follows them into a high-rise building, he is captured, leading to a harrowing interrogation session. This encounter is a relentless display of psychological manipulation, where his captors employ a devastating cocktail of LSD and physical abuse to bend his will. However, Jerry, tenacious and resourceful, manages to escape by inflicting significant harm on his interrogator.

Things escalate quickly as Jerry finds himself re-captured and subjected to troubling psychological tactics, including being put into a drug-induced coma. In a surprising twist, he manages to convince Alice to unknowingly swap his medical chart with that of a dangerous criminal in an adjacent bed, which buys him precious time to plot his getaway. The following day brings a shocking turn of events when Alice discovers that the wanted criminal she was supposed to monitor has mysteriously died, allegedly of natural causes.

With the CIA, FBI, and other governmental bodies closing in at the hospital, Jerry feigns a heart attack prompting a chaotic escape aided by Alice’s unwitting help. While Alice and FBI Agent Lowry sift through Jerry’s possessions amidst an agency sweep, he slips away, hiding in her car. During their tense journey to Jerry’s apartment, a bolstered fortress replete with extreme security measures, he cautions Alice that someone may be watching her every move.

In a thrilling car chase, Alice narrowly avoids capture by changing lanes suddenly and persuading Lowry to hold off on his pursuit. Upon entering Jerry’s sanctuary, he reveals his secret: he has been publishing a newsletter dedicated to exposing various conspiracies. However, as their partnership grows, genuine danger looms on the horizon. Just when Alice considers dismissing him as delusional, a resounding crash signals a SWAT team’s arrival. Amidst the pandemonium, Jerry ignites his apartment and uses an elaborate exit strategy to evade law enforcement.

Once back at her own home, Alice is jolted by the realization of Jerry’s extensive surveillance of her life, resulting in an explosive confrontation that culminates in her distancing from him. Outside, Jerry faces Lowry, underlining the peril Alice is in, all while armed and on edge. Discovering a pattern of fatalities linked to Jerry’s mailing list, Alice becomes determined to unearth the reality of his tragic past and seeks out the last name on the list, Jonas.

Their investigation leads Alice to reveal Jerry’s sinister origins; he had once been coerced into becoming an assassin through psychological manipulation, only to form a bond with her father and promise to protect Alice. This shocking revelation compels her to join forces with Jerry to unveil a mystery that evolves from perilous to deeply personal. Together, they face relentless foes, culminating in a high-stakes confrontation against Lowry who is unveiled not as an FBI agent but a covert operative involved in a larger conspiracy.

In a nail-biting finale, the fate of both characters hangs in the balance at the Ravenswood Generating Station, where twisted loyalties and true identities are uncovered. Alice’s confrontation with Lowry and an explosive face-off with Jonas raises the stakes to unimaginable heights. In the wake of chaos, Jerry is whisked away in an ambulance following a heartfelt exchange with Alice, who believes his fate is sealed.

Weeks after this harrowing series of events, Alice mourns what she suspects to be Jerry’s demise, but unbeknownst to her, he has orchestrated a clever ruse to remain hidden until he can neutralize the remaining threats of Jonas’ organization. As she rides in the lush Connecticut countryside, a solitary pin—a symbol of their bond—comes into view, hinting at a future they’ll share once the shadows of their past dissipate.

This gripping tale weaves together an intricate narrative of concealment, conspiratorial undertones, and a search for authenticity amidst the chaos, drawing from elements of historical intrigue and subtext that resonate throughout. With echoes of once-dominant narratives like the JFK assassination and Watergate, the film evokes a world where trust is fleeting, and everything may be part of a larger, more sinister design.
