Four women from Shanghai join a cybersecurity team, their gentle blades guarding the nation. They swear to protect the enduring peace of Chinese internet culture. As tourism in Xinjiang experiences an explosive boom, the Shanghai Municipal State Security Bureau selects four women of different ethnicities, ages, and professions to travel to Xinjiang and form a special task force focused on cybersecurity. Their mission is to safeguard ethnic unity, show Xinjiang as it truly is, clean up the online world, protect the people's vital interests, and capture suspects in an unsolved case. As they defend cybersecurity during their aid mission in Xinjiang, they develop an unspoken understanding. They become the best and most loyal partners, and a family unlike any other. Together, they protect cybersecurity, safeguard national security and development, and preserve ethnic unity. Their precious experience also brings them much in return: they discover that life can be restarted in a more meaningful way. There, I am more than just myself. I am also a tiny spark guarding my country. Though faint, I can still shine as bright as day. [Cybersecurity guardians] [A female ensemble spanning multiple generations] [Professional life]
