Minyoung is a shy high school girl suffering from depression and bulimia. She is mercilessly bullied by her classmates, especially the sadistic Taeyong and his posse. One day, she is rescued by a sympathetic classmate who introduces her to transhumanism, a process where electrical shocks to the brain cause a person to "wake up to reality" through electrical baptism. Now, fully empowered, she plans revenge for the boys that have brutally bullied her. But when Taeyong turns up murdered, Minyoung must travel back in time using the Tesla coil to reveal the killer... even if the killer might be herself.
