Ruth (Natalie Press) is a devoutly religious Jewish woman who seeks meaning in her submission to the religious Law. Obedient but troubled, she returns from a seminary in Israel to look after her widowed, dying mother in the family home in North London.
At her mother's request, Ruth seeks to reunite the family by tracking down her estranged brother David (Joel Chalfen), who has rejected his religious past. He reluctantly agrees to return home but on one condition; he won't let his mother know he's there. Instead, he tries to create a new Law, taking things into his own hands.
Their shared family secret and increasingly twisted games constructed around the Biblical Law begin to escalate to violent proportions... Meanwhile, the world around them teeters ever closer to war.
Topical in its examination of the links between belief and violence, Song Of Songs draws on modern European cinema and Biblical sources to explore the "return of religion".
