What Is Margaret About?

The premise of Margaret in 342 words, with nothing given away. The full story follows below.

In the bustling streets of Manhattan, a teenage girl walks a tightrope between the ordinary rhythm of a city that never sleeps and the weight of an event that refuses to fade. Lisa Cohen carries the unsettling sense that a single moment has forever altered her trajectory, and the urban backdrop—its relentless noise, crowded avenues, and fleeting anonymity—mirrors the turbulence inside her. The film’s tone is intimate and tense, a portrait of adolescence filtered through a lens of guilt and paranoia that turns everyday encounters into whispered doubts.

At home, the pressure builds against a backdrop of performance and expectation. Joan, Lisa’s mother, is an actress whose recent rise on stage adds a layer of fragile pride to their household, while her new boyfriend, Ramon, introduces another source of friction. Their conversations crackle with unspoken grievances, and Lisa’s relationship with her father, though less highlighted, underscores a family that is trying to stay connected while each member drifts in their own direction. The domestic spaces feel both intimate and claustrophobic, amplifying Lisa’s sense of isolation even when surrounded by people who love her.

Beyond the family walls, Lisa’s world expands into the halls of her high school, where teachers, classmates, and fleeting romances become the terrain of her search for identity. A flirtatious dynamic with a math teacher and a tentative step into intimacy with a peer reveal a young woman wrestling with desire, responsibility, and the need for validation. Intellectual debates about politics and the state of the world pulse through the corridors, hinting at a mind eager to make sense of larger forces while still tangled in personal turmoil.

All of this unfolds under a muted, atmospheric palette that blends the city’s neon glow with dimly lit interiors, creating a mood that is both contemplative and urgent. As Lisa navigates the tangled web of family expectations, school pressures, and her own haunted conscience, the story invites viewers to linger on the quiet moments of doubt and the fleeting glimmers of hope that may, or may not, lead her toward reconciliation.

Full plot

What Happens in Margaret?

The complete story of Margaret, from the first scene to the last, in 639 words (about 3 minutes). Spoilers throughout.

Spoilers ahead

Lisa Cohen, a 17-year-old Manhattan student, is out shopping on the Upper West Side when she crosses paths with bus driver Gerald Maretti. As she runs alongside his moving bus, Maretti allows himself to become distracted, and a pedestrian, Monica Patterson, is fatally struck. Monica dies in Lisa’s arms. At first, Lisa tells the police that the driver had a green traffic signal, but out of remorse she changes her story later, keeping the truth to herself as she wrestles with guilt.

Lisa’s world at home is uneasy and complex. She has a rocky relationship with her mother, Joan, an actress who has recently found success starring in a play. Their frequent conflicts center on Joan’s theater career and her new boyfriend, Ramon, with Lisa feeling ambivalent about both. Amid these tensions, Lisa finds herself in a back-and-forth discussion with her father about a forthcoming trip to his home, a thread that underscores the unfinished business and strain within the family.

As the days unfold, Lisa’s life takes several turns that pull her in different directions. She flirts with her math teacher, Aaron Caije, and they eventually have sex. She also makes a decision to lose her virginity to classmate Paul Hirsch. In the heat of these experiences, she participates in passionate debates with classmates about politics and terrorism, showing a mind that is probing and unsettled by the world around her. Later, in a deeply personal moment, she confides to Caije, in the presence of another teacher, that she had an abortion and is not sure who the father was, mentioning there were several possibilities. The emotional gravity of these revelations sits alongside the ongoing shadow of Monica’s death.

The emotional center of the story shifts as Lisa confronts Maretti at his home. He pretends to have forgotten the details of the accident, but when confronted again he reveals in anger that he does remember, and believes he did nothing wrong. This confrontation galvanizes Lisa to pursue his firing with a fierce resolve. She does not navigate this fight alone: alongside Monica’s best friend, Emily, and Monica’s cousin, Abigail, Lisa becomes involved in a wrongful death lawsuit against the Metropolitan Transit Authority, aiming to see Maretti dismissed and to secure monetary damages for Abigail as Monica’s next of kin.

The relationship between Lisa and Emily develops in fits and starts; they become close, but the bond is rocky, especially during a later argument in which Emily accuses Lisa of using the situation to inject drama into her life. The social orbit around the lawsuit widens to include Joan and Ramon as well; after an after-show dinner, Ramon’s remark — perceived by Emily as anti-Semitic — strains the group further. Joan and Ramon experience a minor falling out, and Ramon dies of a heart attack sometime after.

As the legal process concludes, the case yields a settlement of $350,000, but the MTA refuses to fire Maretti, citing the concern that firing him could inflame a broader labor dispute. Abigail later reveals that money was the primary motivation behind accepting the settlement, a revelation that unsettles Lisa deeply. In a wrenching moment, Lisa confesses that she sees herself as Monica’s killer, a weight she carries with growing intensity.

In the final stretch of the story, Lisa and Joan attend an opera that Joan was scheduled to see with Ramon before his death. On the way, Lisa spots Maretti driving the same bus that had ended Monica’s life, sharing a brief, charged moment with him. Inside the opera hall, Lisa is overwhelmed by the cumulative emotion of all that has happened. She bursts into tears, and in a tender, shared moment, she and her mother reconnect, crying together and holding each other as the performance continues, their bond renewed even as the events of the past continue to loom over them.
