Brother anna (1963)

Andreas, nephew of the abbot of the Monastery of Dionysios, who died eight years previously, arrives at Agion Oros (Mount Athos) with a team of smugglers of antiquities, with the intention of stealing a gold cross set with precious gems, known as the Cross of Alexander the Great. He earns the trust of the meek and hospitable monks. However, a Jewish girl, Anna - whom, while still a baby during the war, her father had entrusted to the care of the hermit Vasileios - continues to pretend she is a young monk. She manages gradually to discover the entire scheme and acts to foil their plot.
