A woman in New York awakens knowing, as deeply as a mother's blood can know, that her grown son is in danger. She has not heard from him in weeks. His name is Jonas. His girlfriend, Vic, doesn't know what she has done wrong, but Jonas won't answer his cell phone. We soon learn that Jonas is isolated in a safe-house apartment in New York City, pondering his conversion to Islam and his experiences training in Pakistan, preparing for the violent action he has been instructed to take in 31 hours.
