It was previously that the great and invincible Emma Mukhina could not live a day without extreme sports - surveillance, chases, ambushes. And now the main activity of the supergirl has become... watching funny dreams. Emma was brought out of the sleepy kingdom by Volodka Vorobyov, who figured out that their astronomy teacher was an alien! He put her under surveillance and discovered many suspicious things. For example, why does the lady visit the “Cool Fishing” store every day, buy earthworms, but doesn’t go fishing?.. And why is she regularly seen in the Virtual Entertainment Center? Having found out what the suspect was doing at this Center, Emma Mukhina perked up: it seems that an investigation can begin! Because planet Earth is in big trouble. And no one but them can eliminate it!..
