Only the Lovers Survived

In Great Britain, a suicide epidemic begins. Every day, more and more adults decide to put an end to it. Soon London is left in the care of teenagers. Ernie and his gang break into sealed apartments, throw parties, and enjoy their freedom. But the supplies of canned goods are dwindling before their eyes, gasoline becomes worth its weight in gold, and power is permanently cut off in the houses. Ernie's gang will have to fight against the powerful Kings who have occupied Windsor Castle. Then, escaping the plague, they will have to leave the city and attempt to survive in a battle against nature. 

Does the new world have a chance for the future?
