S01E01 Crimeless City
Part 1 deals with Woo Jin and his twin brother Beom Gyun. Beom Gyun has been following the tracks of an alien they both saw when they were young. Part 2 is about a murder...
In Part 1, Woo Jin and Jeong Yeon witness what is supposedly a suicide and from the body of the victim comes out a blue bug. They cut it open to find that it’s a microrobot. In Part 2, Joon Hyeok almost catches Bluebird, but he fails as Ho Soo interferes. Ho Soo shouts out that he doesn’t want to remember, and Joon Hyeok says he doesn’t remember anything, so he doesn’t know who he is.
After Aliens arrive, the story takes place in two time streams: 2017 and 2037. In twenty years, and by 2037, the world has been divided into a “Smart Earth” where artificial intelligence has created a utopian environment in which no diseases or crimes exist, and an “Ordinary Earth” where people still suffer from rampant plague and lawlessness.
