The venue for the events is the Mamertina prison in Rome, where Saint Paul was imprisoned because it was considered a threat to the Roman Empire, and Emperor Nero sentenced him to death. Paul’s long journey to this moment has been a full of events. In a certain period of time, when Saul called himself, he persecuted the Christians without ceasing, but then he came to convert to Christianity, and since then he has become one of the persecuted ones. His path involved degradation, torture and drift. In jail, he interacts with one of the guards, Mauritius and the apostle Luke. Mauritius is curious about Paul and seeks to understand how one man can have such an impact on an empire.
