园丁 (2012)

An Iranian filmmaker and his son travel to Israel to investigate a religion that originated a hundred and seventy years ago. Youth from all over come to Haifa to join this religion, and those who serve in the gardens that surround the holy places develop peace-loving attitudes through their interactions with nature.
The filmmaker shares with his son the idea that if the Iranian people had adopted a peaceful religion, Iran would not be preparing a nuclear attack on Israel, but the son believes that all religions tend to bring about destruction. As a result of these arguments, father and son separate from one another and pursue their own paths.
