In 2025, free will can no longer be taken for granted. New economic powers have risen from the ashes of old civilization and 90% of the population have brain implants. The new world order excludes any disobedience against the authorities.
The few who don't have brain implants soon find themselves dealing with the Agency for Tracking the Untraceables. Among these fugitives without home or country exists a small group known as the Yuyuan.
Planning to launch a bold effort against the tyrannical ruling powers and change the future of humankind, they face the Agency and their ruthless director, Shimi Levy, who will do everything in his power to stop them.
