The After-School Detectives are excited: they have been invited to the Invention Fair! They have always enjoyed this event, but this time they won’t find it so enjoyable - the intelligent building where the fair takes place has gone mad! Or it seems so, because its automatic machines and robots are acting in a very irregular and dangerous way. The director of the fair is convinced that someone is sabotaging the event.
Our heroes will have only a few days to discover what is happening, while they face inventors, androids and... ninjas? Will they be able to solve the cybernetic enigma and make it out of this risky adventure?
