Based on a little-known true story, Un Traductor takes place in late-1980s Havana, when children affected by the Chernobyl nuclear disaster are sent to Cuba for medical treatment. Malin, a Russian Literature professor at the University of Havana, is abruptly ordered to leave academia and work as a translator inside a local hospital, caught between Cuban doctors and the families of young patients arriving from the USSR. Torn from the abstract world of teaching and thrust into the relentlessly real world of medicine, Malin struggles to adapt as the emotional weight of the job begins to consume him. But as he spends more time with the children, an unexpected connection forms, one that gradually cracks open his guarded interior and changes how he sees duty, compassion, and survival. Set against a backdrop of Havana on the brink of economic crisis, the film blends intimate personal stakes with a powerful historical context, revealing how one man's mandated assignment becomes a profound reckoning with suffering, responsibility, and human resilience. This trailer offers a moving glimpse into a story where translation becomes far more than language: it becomes a lifeline.
