But an alarm goes off during the robbery and they escape into a nearby church. They hold the police at bay by taking the Pastor and the elders hostage by gun point. Outside, the LAPD try to avoid another public relations disaster by keeping the hostage situation quiet and the local media away. Inside, the Pastor and the elders do their best to ease a potentially dangerous situation with their good-natured, spiritual guidance. Eventually, the church members become a new family to the desperate sisters, who have learned to trust in the Lord. But will the Lord provide HIS own Grace & Mercy for these two desperate siblings?
