At the Presidio Army base in San Francisco, a shocking event unfolds when MP Patti Jean Lynch, portrayed by Jenette Goldstein, is tragically shot while probing a break-in on the base. This grievous incident escalates as two San Francisco Police officers also lose their lives during the fugitive’s escape. In the wake of this chaos, Inspector Jay Austin, played by Mark Harmon, is dispatched to lead the investigation. However, tension emerges between him and Lieutenant Colonel Alan Caldwell, embodied by Sean Connery, who serves as the base Provost Marshal.
The historical roots of this conflict run deep; years prior, Austin and Lynch were comrades during their service as MPs, with Caldwell as their commanding officer. A pivotal moment occurred when Austin arrested Colonel Paul Lawrence, but Caldwell notably failed to extend his support, resulting in Austin’s humiliating demotion and subsequent departure from the Army. The air is thick with mutual disdain as Austin and Caldwell, despite their contentious history, find themselves forced to collaborate when the murder investigation points toward Lawrence as a potential suspect.
As the investigation unfolds, it emerges that Lynch’s murder weapon was a Russian-made Tokarev pistol. Lawrence, who claims to have lost his own Tokarev during a poker game, becomes the focal point of Austin’s scrutiny. Further complicating matters, it is discovered that the getaway vehicle used by Lynch’s assailant is registered to Arthur Peale, a wealthy civilian with shady connections to a holding company. Austin’s attempts to interrogate Lawrence are thwarted by Caldwell, leading him to suspect Caldwell’s intentions are purely protective towards his fellow officer, even amidst allegations of murder.
Navigating the delicate balance between their respective jurisdictions—Caldwell’s over the base and Austin’s over San Francisco—the two reluctantly join forces to uncover the truth. Caldwell proposes that if the ballistic evidence matches the Tokarev fired by Lawrence, he would ensure that Lawrence is handed over to Austin for arrest. Their next stop is a confrontation with Peale, who maintains his innocence, claiming his car was stolen while offering an alibi for the night Lynch was killed. However, Caldwell’s investigation reveals that Peale’s past includes time served in the CIA—a fact that raises further questions regarding his connection to both Lawrence and their shared history in Vietnam.
The tension escalates as Austin receives confirmation from the ballistics report that Lawrence’s firearm is indeed the one that killed Lynch, igniting a reckless pursuit that leads to Lawrence’s untimely death in a hit-and-run incident. Caldwell’s fury at Austin for neglecting their agreement exacerbates their pre-existing friction, heightened further by the revelation that Austin has started dating Caldwell’s daughter, Donna, played by Meg Ryan. This relationship is tumultuous; Donna oscillates between playful banter and emotional distance, underscoring the strain it places on the already fraught dynamic between Austin and Caldwell.
In the backdrop of these unfolding events, Caldwell seeks solace from his confidant, retired Sergeant Major Ross Maclure, significantly portrayed by Jack Warden. Their conversations reveal Caldwell’s admiration for Maclure, who was instrumental in saving Caldwell’s life during their Vietnam service, earning the Congressional Medal of Honor for his bravery. However, as Caldwell and Austin delve deeper into the investigation, they discover a pattern—Lynch’s murder is intricately tied to a smuggling operation involving a stolen water bottle.
When they trace the breadcrumbs back to the water delivery service linked to Peale, the conspiracy begins to crystallize. Spota, a driver at the water company, emerges as a crucial character, having served under Lawrence in Vietnam and being intricately involved in the smuggling of precious cargo hidden within seemingly innocuous water bottles. The stakes rise as they uncover the dense web of deceit involving Spota, Lawrence, and Peale, compounded by the shocking realization that the diamonds hidden within the water bottles—symbolizing not just illicit trade but betrayal—were the ultimate motive behind the chaos that ensued following Lynch’s murder.
As the climactic confrontation unfolds within the water company, Maclure’s surprise entrance escalates the tension, ultimately leading to a violent shootout where Caldwell and Austin must battle Peale and his goons. Despite their best efforts, Maclure is tragically fatally wounded in the melee, solidifying the heart-wrenching repercussions of their investigation. In the aftermath, Caldwell makes the commendable decision to wait before filing the police report, wanting to honor Maclure with the dignity he deserves, a tragic yet honorable way to pay tribute to a life lost in the line of duty.
In the poignant final scenes that unfold at a military cemetery, Caldwell delivers a heartfelt eulogy for Maclure, finally facing the emotional weight of their shared past and the duties they each hold dear. Through his poignant eulogy, Caldwell’s relationship with Donna begins to mend as they come to terms with their tumultuous pasts, allowing them to embrace a new chapter together. Amidst the tears and heartache, a sense of resolution begins to emerge, hinting that even amid grief and loss, bonds can be reforged and forgiveness can pave the way for healing.

Discover the spoiler-free summary of The Presidio (1988). Get a concise overview without any spoilers.
In the fog‑kissed streets of San Francisco, the historic Presidio looms as a living relic of military discipline and hidden bureaucracy. The film opens with the uneasy peace of a bustling base where old conventions clash with the city’s restless energy. Against this backdrop, Jay Austin, a former Army detective who left the service under a cloud of disgrace, is summoned back into uniform to investigate a shocking homicide that has rattled the tight‑knit community. The tone is gritty and introspective, blending the cool, procedural feel of a police thriller with the lingering shadows of past wars and personal regrets.
Reluctantly paired with Alan Caldwell, a stern lieutenant colonel who still commands respect as the base’s Provost Marshal, the two men embody a classic rivalry forged by years of divergent choices. Caldwell’s rigid adherence to protocol sits uneasily against Austin’s more instinctive, outsider approach, setting up a tension that fuels both the narrative drive and the film’s moody atmosphere. Their partnership feels less like a partnership and more like a careful truce, each man wary of the other’s methods while forced to lean on a shared sense of duty to the institution they both love and despise.
Complicating their uneasy alliance is Donna, Caldwell’s independent and spirited daughter, whose budding relationship with Austin adds a personal layer to the professional stakes. Their connection hints at a fragile bridge between old loyalties and new possibilities, suggesting that the investigation will test not only the characters’ resolve but also the bonds that tie them together. The film’s mood hovers between tense investigation and quiet, character‑driven moments, inviting the audience to wonder whether trust can be rebuilt on a foundation of old wounds and whether the truth hidden within the Presidio’s walls can ever truly be uncovered.
