A 33-year-old rural female teacher takes over the worst class in the school, and right after taking office, she finds out she is pregnant with triplets. Her husband tells her to get an abortion and quit being the head teacher, but she insists that "good students and poor students are all to be born." Three troubled students go from leading disruptions to pedaling a tricycle to the examination room to send her to give birth, the poor class fully counterattacks and advances in schooling, and the triplets are safely born. Teachers and students run toward each other in both directions.
