Jung Soo-yeon, a first-year elementary school teacher, experiences an absurd situation after school when she gets trapped on the school rooftop by her 5th-grade students' pranks. The children lock the rooftop door, mock Soo-yeon, and leave, and Soo-yeon tries to call for help in the empty school but no one is there.
