About the series
Ha Dong-soo (Jung Hae-in) is part of a new human race called Connect. Connected beings never die. One night, Ha Dong-soo is kidnapped by a group of human organ traffickers. They cut out his eye. Soon he starts seeing something and realizes that the person who has his stolen eye is a serial killer. Ha Dong-soo can now see what the killer sees and pursues him to stop him from killing people. The stolen eye was transplanted into Oh Jin-seob (Go Kyung-pyo), who appears to be a polite and competent employee at work, but is actually a cold-blooded serial killer. Based on the webtoon of the same name by Shin Dae-sung.
