As big-hearted patriarch David clings to a deal that could save both his ailing catering firm and his cherished standing in the Edgware Jewish community, his children are at loggerheads.

"You must have heard him banging on about the long line of Rosenbergs, stretching back to the Bible. He reckons some ancient relative catered the Last Supper."

While eldest son Danny fights for the Israelis in Gaza, his sister investigates war crimes in the same conflict. Their brother drinks and brawls and refuses to join their father's business. But when tragedy strikes, each family member is forced to confont head-on the clash between individual identity and the demands and expectations of community.

The Holy Rosenbergs explores tribal loyalties, the culpability of family and the consequences of standing up for what you believe to be right.
