To achieve that scope, the crew spent 12 months embedded in emergency departments at 10 hospitals nationwide, filming more than 140 days and following the full chain of care from emergency rescue to in-hospital multidisciplinary collaboration.
The result is a sweeping relay of life: a village doctor in the Inner Mongolia autonomous region initiating a "life highway" for a stroke patient; a helicopter in Zhejiang province airlifting a severely injured young man; teams across regions coordinating seamlessly to save patients after high falls. Behind each dramatic moment lies a web of protocols and cooperation that turns "time is life" into practice.
Grassroots village doctors left the deepest impression on Zhang. "They are not only guardians of health, but also providers of emotional comfort. That is crucial."
With the advancement of digital healthcare, their role has become even more pivotal. "We filmed the 'mobile hospital' general practice support package, through which specialists in Beijing and Shanghai can conduct remote consultations. In such cases, village doctors become the indispensable safety net of digital healthcare."
She notes that many villagers are elderly and speak dialects, making village doctors essential intermediaries. "This trust is built over years of interaction. At its core, the doctor-patient relationship is about entrustment — 'I trust you with my life'. Medicine is full of uncertainty, especially in emergencies where patients are on the brink of life and death. Such trust is essential."
In Jianshe village of Dalad Banner in Inner Mongolia, Zhang observed tangible results: Over the past five years, dozens of heart attack patients received timely stent procedures, and remarkably, none died from a heart attack or stroke, which is a testament to both the skills of the village doctors and the strength of the emergency system.
Conveying doctors' professional conviction is central to her work. "It is no exaggeration to compare doctors to soldiers in peacetime. They are the ones who rescue and protect our lives, pulling patients back from the brink of death. Such a profession requires unwavering faith."
She adds: "Doctors must face the possibility of ultimate failure, yet continue working with all their strength. That is its greatness… we must give everything we have; that is what I most want to highlight."
That sense of mission, she says, is often quiet but absolute. "An emergency doctor resting at home may receive a call and rush back to the hospital in pajamas. For them, it is not about showing off; it is a sense of mission."
And much of that mission remains unseen. "Behind every life saved, every diagnosis analyzed, and every solution devised, there is immense effort that patients do not see. We want to reveal that, so ordinary people can better understand and appreciate this profession."
