 Macky rescues a snobbish, aristocratic Roman girl, Portia, from her runaway horse and she is so fascinated with Macky and the whole world of Alexandria s Delta Quarter ghetto, that she returns and hires Diana to make a dress for her - at the Governor s palace! Rebecca is horrified that a Roman should enter their lives and uses the story of how Delilah led Samson astray to warn against being corrupted by foreign ways. But Macky senses there is more to Portia than they have seen so far. Diana teaches the youngsters the value of tolerance through the story of Peter s friendship with Cornelius, the Roman Centurion - and with help from their new Roman friend Portia, the gang thwart an extortion scheme run by Tobias and his sergeant, Brutacus.
