In the future, when an ecological disaster made the earth uninhabitable, people began to live underground and on other planets. Then people invented a time machine in order to travel in time to correct the past, thereby correcting the future. And they travel into the past in a ship - a time machine. Parrots - Drones from this ship fly and deliver message bottles everywhere. In the bottle there are fish and jellyfish robots that begin to speak a message when you open the bottle. This message is about how people need to take care of the ecology of the planet in order to preserve our planet and prevent an ecological catastrophe in the future.
