In 1999, doctoral student Ingmar Hoerr accidentally discovers revolutionary mRNA vaccine technology at the University of Tübingen, Germany—the same technology that would later protect millions from Covid-19. Despite initial ridicule from Nobel laureates and experts, Hoerr perseveres and founds his own company to develop the first vaccine based on mRNA technology. With the Covid-19 pandemic emerging in 2020, everything changes. Suddenly, governments and people around the world pin their hopes on the technology he invented, believing it could save the world. But when Hoerr is called to Berlin by the German government, fate intervenes and his focus shifts from saving humanity to saving himself.
