On a spring afternoon in 1983, a high school student discovers that there is a correspondence between the 27 letters of the Greek alphabet and numbers. This will lead him on a constant search, which will result in proving that the Greek language is not different from other languages only because it has primacy, musicality, and mathematical structure, but also contains encoded information, knowing the laws of cosmic creation and the sciences, as well as the numerical values ​​of mathematical constants.

In April 2013, during an excavation in Crotone, Italy, a group of American archaeologists and other scientists discover the ancient Pythagorean school.
In the two underground levels of the excavation, the archaeological team discovers some peculiar sculptures, which are filled with encoded representations, containing mysterious combinations of various letters of the ancient Greek alphabet.

In their attempt to decode them, the three scientists of the mission discover a Greek mathematician, whom they believe has the ability to decode all these ancient riddles. The head of this scientific team is a mysterious American tycoon, who will eventually bring the Greek mathematician to Crotone and immediately after, a great struggle will begin to decode the inscriptions, with the aim of discovering the third underground level, where ancient secrets of the utmost importance have been hidden for many centuries.
