Rouzbeh arrives in Prague, far away from his troubled family life in Tehran, and immerses himself in a research into his father’s past as a communist expatriate in Czechoslovakia. Upon visiting the flat where his father lived 50 years ago, he is stopped by a policewoman who’s investigating a recent accident involving the current flat’s resident: his name was Vladimir and he has fallen out of the flat’s window. When he finds out that Vladimir’s father was also an Iranian, with the very same name as his own father, Rouzbeh is suspicious of the family history he thought he knew.
