Bebawi: The Via Lazio Murder retraces the killing of an industrialist in 1964 and the attempt to bring to justice the two perpetrators who managed to escape after the first trial.

In the slums of Naples, a prostitute, when questioned by police about the death of one of her clients who fell from the gutter, claims it was an accident. Later the woman gives another version, accusing the owners of the boarding house of being murderers. A trial will begin that will decide which side is the "truth."
