premise: The Assassin of Rome (Italian: "Girolimoni, il mostro di Roma" ) is a 1972 Italian historical drama film directed by Damiano Damiani. The film tells, with some historical licenses, the story of Gino Girolimoni, wrongfully accused of a series of child murders that occurred in Rome between 1924 and 1928.
hypothesis: The Assassination of Rome was a film that told the story of children who were murdered by Damiano Damiani. 
reason: The film was called The Assassin of Rome, not the Assassination of Rome, and it did not tell the story of children who were murdered by Damiano Damiani, but rather, a story of a man who was wrongfully accused of child murders.
