Plus Q&A with director Kim Sangchan.
Addiction Karaoke is run by Sung-Wook. When business is slow, he hires a singing helper Ha- Suck, a girl in her early 20s, to boost sales.
She’s a hopeless game addict, but somehow lures customers in with her mysterious charm. Na-Ju, a professional helper, joins the crew and brightens up the miserable place with her bubbly character.
Just when everything starts turning for the better, little do they know that a serial killer on the loose in town is after something in the karaoke.
