He is about to leave Tehran for good to go back to his hometown by the name of Darab, when he comes across young university student Roya Atabaki (Sahar Jafari-Jozani) who is researching for her final year dissertation, which is regarding the period 1198–1203, that is said to be a period of turmoil for Iran's ruling elite.

The coffee (which is bitter) is ready and he duly drinks it, his sight becomes hazy, and when he manages to refocus he is in the year 1201 (1822 AD), and the story develops therein.
