Qui arrêtera Cyanure?
 Swindled by a shopkeeper, Fantasio finds himself in the possession of a strange automaton able to take photographs. Apparently intelligent, the machine quickly escapes from its new owner. Spirou and Fantasio follow it to Champignac, where the automaton stops in an old unused railway station. There, they discover a bound and gagged young woman, whom they untie. She appears hostile and flees after destroying the station's interior. The owner of the place, Caténaire, a former station master, discovers the chaos when he returns and explains everything: the robot that Fantasio bought, Télesphore, was his first invention, while the woman which they freed is a more advanced android, Cyanure, evil and endowed with powers to control electrical machines. Cyanure tries to invade the village with an army of robots built in the nearby factory Roboc Inc.. Spirou and Fantasio mobilise a resistance, made up of the children of Champignac, and together they defeat the android and her army. <!--
