In the Lublin ghetto, in an attic, there is the kingdom of Henio, a Jewish child. He has a secret and he also shares it with his best friend who is not Jewish. Behind the dusty glass of one of the dormer windows a wonder is hidden: a different world, perhaps a place of peace, different from the horror of war that can be seen from the other window. For those who are Jews the time has come to escape. So on the night of March 16th Henio runs to his friend to convince him to run away together, but he is afraid and stays. On the morning of the roundup Henio disappeared. His friend looks for him everywhere, even in the attic, where a big surprise awaits him: children's footprints on the window glass and a name that is a greeting. Pierdomenico Baccalario and Alice Barberini give us a moving story to remove the dust from the history of the Lublin ghetto and imagine a different epilogue, also for Henio Zytomirsk.
