The lovably simple residents of peaceful Kikoriki Island are thrown kicking and screaming into big adventure, when their resident scientist invents an amazing device - a helmet called "the Improverizor," which takes personality traits from one person and swaps them with traits of someone else. But when spineless young Wally tries to use the untested device to cure his cowardice, he ends up even more spineless - by getting accidentally body-switched with a squirmy little caterpillar. Now he has even more to fear than he could have ever imagined, and so do his fellow villagers, as they're dragged into a madcap adventure packed with plane crashes, mistaken identities, erupting volcanoes and angry primitives on the warpath. Boy, do the Kikoriki Crew wish they could switch place now - with anyone.
In the not-so-distant future the computer game industry reaches its fullest flower. Virtual reality is indistinguishable from real life. The government launches Department C to control the game space. Censors secretly delve into games. Their mission is to take sex and violence beyond the forbidden level. A game that would let them do that must be banned. One of the Censors is a good guy who hates his bloody job. The other one is a creep. But even the Censors lose their ability to tell the game from the real world.
