Arthur goes to the grocery store when a robbery takes place. Frank, a policeman, is injured and Arthur drives him with his van to the underground car park of his building. Arthur discovers a large stock of bottled water inside Frank's van.
Emma, Darren and Arthur are ready to leave their building when they are attacked by the gangsters who robbed the grocery store. Frank defends the group before they are forced to flee with the van.
The city is now chaos and violence. In the van, Frank reveals the real situation: the water cut is nationwide. Because of a flat tire, the group is forced to stop. They find refuge in a warehouse where they are preparing for the worst.
As the group changes the tire, gangsters attack. During the shooting, because of Darren, Emma is seriously wounded. Frank, Darren and Malika flee the fight abandoning Arthur and Emma.
