Petro-chemist Andy Nielsen knows how dependent the world is on oil; if something were to happen to the world’s oil supply, it would set off a chain reaction: transportation would grind to a halt, supplies would cease to be delivered, law enforcement would be overwhelmed. While on a business trip to the Middle East, Andy realizes that his worst fears are coming true and his family is separated at this crucial moment. His teenage daughter, Laura, is alone at home in London while his wife, Elena, and young son, Sam, are in Paris. Amid this chaos, each family member will sacrifice everything to find one another, despite the distance and the dangers that separate them. Based on Alex Scarrow’s best-selling novel of the same name.
