Nuns of the 'Sisters of Mercy' convent in the middle of the West Bank wilderness have their daily routine of silence and prayer disrupted when a family of religious Israeli settlers crash their car into the convent's wall. The Sabbath is approaching and they need to get home urgently however because of the Sabbath laws the Israelis can't operate a phone to call for assistance and the Nuns have taken a vow of silence. Together they have to come up with an unorthodox plan to help them get home.
