Milan is a Belarusian immigrant who arrived in Rome with the dream of being able to change his life but, unable to take advantage of his degree in engineering, he finds work as a fake centurion, in front of the Colosseum and dealing with the crowd of tourists with whom he has his photo taken. His employer is Sergio, a former stuntman and self-styled invalid who is busy with a thousand imaginative jobs just to make some money and who shares a house with his sister Maria, a hotline operator. As the competition in front of the Colosseum becomes increasingly tough, Milan devises a plan to defeat everyone and, using his university studies, builds a real chariot with which to attract as many customers as possible.
