What Is Silent Friend About?
The premise of Silent Friend in 256 words, with nothing given away. The full story follows below.
In the serene grounds of a German university, an ancient ginkgo tree stands as a silent witness to centuries of human drama. Dating back to 1832, this majestic presence in the Botanischer Garten Marburg has offered shade and solace to generations of scholars, dreamers, and seekers—each leaving their trace while the tree quietly observes their private lives.
In early 2020, neurologist Dr. Tony Wong arrives from Hong Kong to pursue research at Marburg University, drawn by the institution’s reputation and the garden’s tranquility. His work takes an unexpected turn as circumstances force him to adapt to unfamiliar surroundings. Under remote guidance from colleague Dr. Alice Sauvage, Tony finds himself increasingly captivated by the ginkgo tree, sensing possibilities that extend beyond conventional science.
The tree’s memory reaches further back—to 1908, where Grete, a determined young feminist, challenges the university’s entrenched traditions by seeking admission as its first female student. Her moments near the ginkgo become a sanctuary as she confronts an academic establishment reluctant to accept her intellect. Decades later, in 1972, solitary student Hannes finds his own refuge beneath the branches, his life intersecting with fellow resident Gundula, whose research on plant-human interplay quietly challenges his professed indifference toward the natural world.
Across three distinct eras, lives converge around this single, enduring presence. Each generation discovers that the garden holds more than botanical specimens—it cradles stories of connection, isolation, and the delicate bonds that form between people and the living world around them, all under the patient gaze of a tree that has seen it all.

Spoilers ahead
In early 2020, neurologist Dr. Tony Wong, Tony Leung Chiu Wai, travels from Hong Kong to Marburg to continue his research on newborns’ brain activity at Marburg University. But shortly after his first class, the COVID-19 pandemic disrupts his plans. Forced into lockdown, he adapts to a new life and grows fond of the nearby Botanischer Garten Marburg, where he becomes attached to an ancient gingko tree dating back to 1832. Guided by video calls with Dr. Alice Sauvage, Léa Seydoux, he develops a novel approach that attempts to correlate his neural signals with the tree’s activity. With a makeshift brain scanner mounted on the tree, he senses a possible link between what is seen and what remains unseen. Trouble arrives when Anton, the campus janitor, Sylvester Groth, grows distressed by the project and destroys the equipment. Alice responds by sending the male form of the gingko’s gymnosperm to fertilize the campus’s solitary female. After the equipment is damaged, Anton begrudgingly comes to terms with Wong, offering him a local German dish. Together, they watch the fertilization process unfold through the scanner, pondering the delicate balance between science and nature.
In 1908, Grete, Luna Wedler, a young German feminist, seeks to become the university’s first female student. During her interview, the botanic department’s board attempts to humiliate her with sexist questions about Christian Konrad Sprengel’s plant reproduction theory. Distressed but prepared, Grete answers calmly and, drawn to the garden’s quiet spaces, she seems to connect with the old gingko tree. She is found by Thomas, who reveals that she was the only woman accepted by the committee. After attending a female group gathering at the gingko tree, in the early morning hours, Grete is expelled from a family home where she rented a room, accused of promiscuity. Sheltered by Herr Fuchs, who hires her as his assistant photographer to his studio, Grete discovers a passion for professional photography, capturing her research subjects with growing confidence. At the University, she applies to join Thomas-led college trips to the East Indies, offering her work as a professional photographer.
In 1972, solitary student Hannes, Enzo Brumm, lives in a shared student housing near the campus, but spends most of his free time reading at the botanical garden near the gingko tree. One of his housing partners, Gundula Marlene Burow, researches the interplay between plants and humans, while Hannes claims indifference toward natural studies due to his rural upbringing and the farm work he endured in youth. As he develops feelings for Gundula, he tries to connect with her through Goethe’s Metamorphosis of Plants, but she rebukes him for his lack of knowledge. During a campfire with Gundula and friends, she questions whether he would have sex with her since he’s supposedly still a virgin, to which a confused Hannes denies. Gundula leaves for a college trip, leaving him responsible for her research, which includes watering her plants and a purple geranium connected to an activity sensor. Hannes’s loneliness draws him closer to the sensor-equipped plant; by refining the sensor, he enables it to open the small gate of the residence. But a postcard from Gundula announcing her relationship with Peter leaves him shaken.
