Late 1800s, in Italy, Guglielmo and his brother Alfonso welcome their cousin Daisy coming from Scotland to spend her holiday in their Villa Griffone surrounding by nature in the hills south of Bologna. They need to find the way to be in communication at a distance when she has to come back home far away after the summer. Guglielmo leads the experiments, helped by the other two. His research covers all scientific fields, from chemistry to electricity and the refraction of sound waves, based on the elementary and intuitive physics. He is inspired by the real story of the inventor Guglielmo Marconi, the wireless pioneer.
