79 AD. In the city of Pompeii the young Glaucus loves beautiful Jone, although he's courted by Giulia and secretly loved by his blind slave Nidia. One day Glaucus is wrongly accused of murder by a priest of Isis, Arbace, who wants to marry Jone and please Giulia. Glauco is condemned to be devoured by lions in the arena of the city, on that very day the erupting Vesuvius. Jone ovvero gli ultimi giorni di Pompei (1913) was one of two major Italian productions of The Last Days of Pompeii done in 1913, and not to be confused by the more famous Gli ultimi giorni di Pompei (1913).
