The main plot revolves around the Triwizard Tournament, a magical competition that hasn't been held for centuries, and Hogwarts has been selected to host it.

The Cup transports Harry and Cedric to a graveyard in Little Hangleton. There, Wormtail kills Cedric Diggory on Voldemort’s orders and uses Harry's blood to perform a dark ritual that restores Voldemort to his physical body.
