An Iranian filmmaker and his son travel to Israel to investigate a world religion with around seven million followers, which originated in Iran about a 170 years ago. Youth from all over the world come to Haifa, the center of this religion, to serve. Those who serve in the gardens that surround the holy places develop peace loving attitudes through their interactions with nature. As the father accompanies a gardener from Papua New Guinea, he finds similarities between the teachings of this religion, which was born in Iran, and the ideas promoted by people like Mandela and Gandhi. He shares this idea with his son, who 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.
