One day, a caterpillar was caught by a boy. Caterpillar is in the bottle, so he can't get out from there. In boy's room, there are many specimen. Caterpillar doesn't want to die and be specimen, so he tried to escape from the bottle but he couldn't.
On the evening, mantis came to the room. Mantis wants to help that caterpillar, but couldn't. Then, mantis did some gestures. It seems that caterpillar would be killed by the boy. When mantis tries to fly away from the wind, boy caught the mantis.
After that, I couldn't seen the caterpillar. Maybe the boy would have set the caterpillar free. Mantis is in the bottle. There is a lid and he couldn't get out from the bottle. Just then, a butterfly came into the room. Once flew away, but soon came back with many friends. They made strong wind and helped the mantis.
I think the theme of this film is the importance of kindness. If we help someone, we would be helped someday.
