An educational animated film about science. Mira, who studies solar cookers, Kang-min, who is developing a robot, and Hong-man, who is researching a growth stimulant for rabbits, are elementary school classmates. However, Mira can barely cook a bowl of ramen with her solar cooker, and Hong-man causes a disaster, killing a large number of rabbits with an improper growth stimulant. Coming from a poor family, Hong-man has high pride and refuses to ask for help, continuing his research alone. Exhausted by repeated failures, he eventually collapses and is diagnosed with an incurable disease. Kang-min and Mira participate in the Presidential Science Invention Contest on behalf of their friend and win the Minister of Science and Technology Award and the Presidential Award. However, unaware of this, Hong-man is hovering between life and death.
