Achilles is a very intelligent boy with a creative mind who stutters and expresses himself by building bizarre and fantastic toys. Having tried almost everything to help Achilles get over his stutter, his family decides to take him to Villa Agora, a summer clinic run by Dr Aglieri, the inventor of an experimental "sing-talk" method. Life at Villa Agora is a series of funny and poetic situations until the final test that Dr Aglieri considers as the final and most tangible demonstration of the validity of his method. It consists in taking the patients to a big shopping mall leaving them for thirty minutes alone. During that time they must show that they are able to communicate with the strangers around them.
