What Is Twenty Plus Two About?
The premise of Twenty Plus Two in 333 words, with nothing given away. The full story follows below.
In the polished world of a Hollywood fan club, a shocking murder rattles its inner circle and uncovers a hidden trove of newspaper clippings about a vanished heiress. The dead secretary’s desk becomes a cryptic puzzle, offering twenty tantalizing clues that hint at a long‑forgotten disappearance and raise the unsettling question of whether someone finally uncovered a buried truth. The atmosphere crackles with the glamour‑and‑grit duality of Los Angeles, where fame masks a labyrinth of secrets waiting to be untangled.
Tom Alder is a Los Angeles private investigator who has made a career of locating lost heirs. Known for his methodical mind and a war‑scarred past, he is summoned by a police friend to probe the murder that has set the fan club on edge. His expertise in tracing forgotten lineages draws him into a case that feels less like a simple homicide and more like a ghost story echoing from a New York boarding school thirteen years earlier. As he follows the faint trail of clues, the city’s neon sheen and shadowed alleys blend into a noir‑toned backdrop that mirrors his own relentless pursuit of answers.
Linda Foster reappears in Alder’s life, a striking woman whose past connection to him adds a personal layer to the investigation. Meanwhile, Nikki Kovacs—another captivating figure—enters the picture, her presence on a tense transcontinental flight sparking an instant, cautious intrigue. Their overlapping worlds of wealth, influence, and hidden histories create a delicate dance of attraction and mistrust, promising that the search for truth will be as much about navigating complex relationships as it is about following evidence.
The film moves between the glitter of Hollywood, the cold corporate corridors of New York, and the expansive plains of the Midwest, all rendered in a moody, atmospheric style that refuses to sanitize the human cost of long‑kept secrets. Against this richly textured setting, Tom Alder finds himself pulled deeper into a web where every clue could illuminate a new facet of the past—or plunge him further into darkness.

Tom Alder is a Los Angeles private investigator who specializes in locating lost heirs, and he’s drawn into a case when a police friend asks him to probe the murder of a movie star’s fan club secretary. The inquiry sparks interest in a long-quiet mystery: the disappearance of Doris Delaney, a wealthy young woman who vanished from a New York City school thirteen years earlier, a case that had cost her father a small fortune and yielded no answers about where she went or why. Alder follows a thread the police overlooked, sensing that the two cases might be more tightly connected than anyone realized.
That hunch leads him straight to a Hollywood legend: Leroy Dane, a charismatic action star with a polished public image but a shadowy underside that could hide dangerous secrets. As Alder digs deeper, he is drawn back into the orbit of Linda Foster, a woman who once sent him a Dear John letter during his years in the Korean War and who now moves in circles of wealth and influence, complicating a case that was already tangled. Linda’s path crosses with Nikki Kovacs, a striking woman in her late twenties whose friendship with Linda adds another layer to the mystery and who instantly captures Alder’s attention on a tense plane ride to New York.
On that flight, Alder sits beside Nikki and begins a careful, wary conversation that soon broadens into a web of acquaintances, debts, and past regrets. In his hotel room, he is approached by the savvy conman Frenchy Pleschette—a man who has spent half his life in prison and who tries to hire Alder to find his missing younger brother, first with a tempting offer and then with a threat. Alder refuses the lure, yet the encounter foreshadows the perilous depths of deceit he is stepping into.
Alder’s demanding interview with Mrs. Delaney, the mother who clings to the belief that Doris is still out there somewhere, reveals more than just grief. She speaks with a stubborn conviction that Doris would have left some sign, some clue, if she had died, and Alder’s patient, insightful approach gradually wins her trust. He learns that Mrs. Delaney’s certainty about her daughter’s survival is not merely hope but a stubborn, loving belief that shadows the investigation.
As Linda shadows Nikki to Chicago, the truth begins to surface in fits and starts. Alder recalls a troubling memory from his wartime days in Japan, where a woman using the name Lily Brown hinted at deep, buried troubles—troubles that seem to trace back to Doris Delaney herself. The pieces start to fit: Nikki Kovacs is linked to Doris Delaney, living under a dangerous cover, and Doris’s whereabouts are closer than anyone suspects.
A midwestern rumor mill heats up when Alder’s findings point to Leroy Dane as a prime suspect in Doris’s and the fan-club secretary’s murders. Dane arrives in Chicago and becomes a looming threat, complicating a city already thick with pursuit: Linda’s longtime boyfriend and Nikki’s fiancé descend on the same hotel in pursuit of their respective women, each drawn by the same riddle and the same danger. The convergence of these threads pushes the drama toward a crowded, claustrophobic showdown.
Alder heads to the Pleschette family homestead in South Dakota, tracing the killer’s steps to a place where the truth might finally be unmasked. He arrives first, where he finds Nikki in a raw, unguarded moment and listens as she bares a painful confession: she had been raped as a teenager by a man who used a different name and a different life to lure and victimize her. The trauma of that act—coupled with pregnancy loss and a life marked by secret shame—has haunted her, pushing her into a life far from the one she wanted.
The revelation shifts the stakes: the man behind many disguises is Auguste Pleschette, the brotherly antagonist who has stolen identities and manipulated those around him, including Nikki. In a brutal, final confrontation that pits two brothers against Alder and his allies, Lane (the alias Auguste uses) declares his intent to kill his three pursuers while sparing only his aging father. In a decisive strike, Frenchy shoots Lane before he can finish his deadly plan, ending the immediate threat.
With the killer out of commission, Alder and Nikki find a fragile peace, rekindling the romance that sparked in their shared moments in Japan. Meanwhile Linda is left to chart her own course, stepping out of the crossfire of the case and the lives it has upended. The film closes on a note of hard-won resolution, where truth brings closure for some and a renewed, cautious hope for others, all framed by a noir-edged atmosphere that refuses to sanitize the human costs of secrets kept too long.
