Popstars(2016)

Original title: 연습생

Everyone dreams of being a pop star. But the Korean showbiz isn't only fame and glamour. For Mira, a young girl about to make her debut with a girl group, the dream turns into a nightmare. Always smiling in front of the camera, but pressure, competition within the group, and a busy schedule are taking their toll. And if that weren't enough, somebody seems to be threatening her. Or is it all just in her mind?
