Darren Shan and his two schoolmates are excited when their friend Steve comes across a flyer advertising the Cirque Du Freak. The boys pool their money but can only purchase two tickets, so they play a game of chance to see who will go with Steve. Darren closes his eyes, and almost as if by magic, the ticket floats into his hand.
Darren and Steve are mesmerized by the fantastic and disturbing show, but when they get caught up in a deadly trap Darren must make a deal with the only person who can save him. And that person is not human and only deals in blood.
