In the middle of the 21st century, the earth's environment has been devastated, and human civilization and beliefs have collapsed unstoppably. At the juncture of chaos, a technology company named ROC quickly emerged with the "Pilgrimage 7000" intelligent robot they developed. Pilgrims go deep into every corner of the people and help people deal with everything around them from life to death. Under the constraints of the two fundamental principles, the robots worked hard, and at the same time encountered various cruel and merciless treatments. Jack Bogenis an insurance claims adjuster under ROC. During his work, he accidentally discovered that many pilgrims have not only been tampered with privately, but even the fundamental principles have been violated. The robots either hurt others or self-mutilated, making Jack vaguely aware that there seemed to be a conspiracy behind him.
He left the city to search for the truth in a slum, where he saw the magical scene of the robot Claire repairing itself. The persistent pursuit also put Jack in the middle of great danger.
