Lead Children tells a gripping tale of how the world really can be changed for the better — as long as a determined person works relentlessly towards it. Released on 11 February 2026, the show centres on Jolanta Wadowska-Król, a young doctor who strives to turn things around in her community after discovering that a mysterious illness plaguing the children of Szopienice, Poland, is a direct consequence of an industrial operation. But what if we told you that Dr Wadowska-Król isn’t just a figment of the writer’s imagination? Yes, the Netflix Polish series Lead Children is based on real-life events, and here’s its true story.
Helmed by Maciej Pieprzyca, the historical drama spotlights the courage Dr Wadowska-Król (played by Joanna Kulig) displays as she tackles resistance from the authorities, including SB officer Hubert Niedziela (played by Michał Żurawski), while trying to uncover the truth about the Szopienice smelter.
But what, exactly, was the Szopienice smelter? To understand this, let’s rewind the clock to the 1970s and uncover the true story behind the Netflix series Lead Children.
The true story of Netflix’s Lead Children: Who was Dr Wadowska-Król?
Born on 27 June 1939, Dr Jolanta Wadowska-Król was a Polish paediatrician who began working at the District Clinic in Szopienice, Katowice, after completing her specialisation in 1968. Not long after, she began noticing unusual symptoms in several children living in the working-class neighbourhood of Szopienice.
On closer examination, she discovered that these symptoms pointed to something far more serious than a common illness: they were the direct consequence of widespread saturnism — severe poisoning caused by prolonged exposure to lead. She then identified the source of this horrifying public health scandal: a nearby foundry, an industrial facility responsible for producing various metal components.
Realising that an entire generation’s health had been severely compromised, she reported her findings to Professor Bożena Hager-Małecka, the then head of the Paediatrics Clinic at the Silesian Medical University in Zabrze.
Determined to help the young victims, Dr Wadowska-Król closely monitored three areas of Katowice — Szopienice, Burowiec and Dąbrówka Mała — conducting thorough medical examinations of the children living there. Her reports suggested that the scale of the problem was far greater than anyone could have imagined.
Knowing they were racing against time, Dr Wadowska-Król, with the support of Professor Hager-Małecka, published her official findings in a doctoral dissertation in 1974, hoping to warn as many people as possible.
Unfortunately, this did not go down well with the government of the day, which was desperate to avoid the controversy.

What happened to Dr Wadowska-Król once she published her findings?
Once Dr Wadowska-Król made her research public, life, as she knew it, changed forever.
The Polish United Workers’ Party, the communist ruling party, did not want her to raise the alarm and tarnish Poland’s industrial image. Determined to force her to back off, the authorities hindered her at every step. When the threats and repeated warnings failed to do the job, they prevented her from giving her PhD defence. But they didn’t stop there — they also ensured that the dissertation Dr Wadowska-Król had worked on so tirelessly completely disappeared.
Despite the obstacles imposed on her by the government at the time, Dr Jolanta Wadowska-Król continued her work, refusing to let the authorities’ recklessness endanger the lives of innocent children.
Ultimately, her grit and determination paid off.
According to a report by the University of Silesia, treatment for youngsters living in close proximity to the Szopienice Non-Ferrous Metal Smelter was arranged. Additionally, in 1975, the Katowice Municipal National Council demolished the houses nearest to the smelter’s chimney. The report also notes that families with children returning from sanatoriums after treatment were moved to flats away from the source of the pollution.
Dr Jolanta Wadowska-Król officially retired in 2011.
Did Dr Wadowska-Król ever receive her doctorate?
Yes, she did!
In 2021, the University of Silesia awarded Dr Jolanta Wadowska-Król with an honorary doctorate. To celebrate her work and efforts, the university also prepared a short documentary titled The Mystery of the Szopienice Children Poisoning, which presents her story.
Dr Wadowska-Król’s interviews, records and research helped thousands of children in Szopienice survive lead poisoning. Although she passed away in June 2023, her work continues to be recorded and preserved through shows such as Lead Children.
