In 2004, archaeologist Georgi Kitov working on excavations in the Valley of Kings opens up a tomb that has not been robbed. The richness of the artefacts is indicative of a royal burial and, step by step, scientists identify it as the burial of Seuthes III. The team comes across another unexpected discovery – a bronze head, a masterpiece of antiquity, buried in front of the tomb’s entrance. With thеse finds and the series of questions and guesswork they provoke as a starting point, the film gradually reveals the psychological portrait of a Thracian king and his role in a complicated age.
