Song Eun-Beom (Baek Sung-Hyun) runs internet website “Albaui Shin” (literally “God of Part-Time Job”), which has about half a million registered users. One day, a debate program is streamed live. A person then threatens to the show that if the debate program is stopped, hostages will be killed. Song Eun-Beom struggles to save his younger sister Eun-Byeol (Kim Ji-Young) and others who are locked in the broadcasting station.
