The story is inspired by a real life fact and set in the 1930s when, at the Institute of Physics of Via Panisperna, in Rome, physicist Enrico Fermi managed to involve a group of brilliant young students—Emilio, Bruno, Edoardo and Ettore (respectively, Emilio Segrè, Bruno Pontecorvo, Edoardo Amaldi and Ettore Majorana, all of whom became famous scientists)—forming a working group committed to scientific research who would achieve great discoveries in the field of nuclear physics.
