The Grand Amir and Donna Maria (1970)

Sinopsis

Maria suffers from the strangest illness; it resembles cancer but with one distinct difference: it somehow connects Maria to the fate of a 15th century woman named Donna Maria. Maria begins to time travel, gradually discovering the absolute brutality of history. She learns that Donna Maria was a Hungarian princess taken to a Bursa harem as a concubine of Ottoman's Sultan.
