A sprint on premiere day. “Look! This is all yours. It’s all yours. Just run. Hold out your hand, Miru. Take it! Run faster!” a voice in her head whispers to start the day. The assistant director’s day is destined to unfold in a series of unfortunate and unlucky episodes: buying metal hair curlers, taking her three-year-old daughter to her grandmother’s, taking an actress who is having panic attacks to an interview. And then Kaspics, one of the main actors in the performance, disappears. Miru has nothing left — a day to live, a premiere to save.
