Harry enters his fourth year at Hogwarts, where he is mysteriously chosen as an underage fourth competitor in the dangerous Triwizard Tournament. After surviving three grueling tasks, Harry and fellow champion Cedric Diggory touch the winning cup, which is a portkey that transports them to Lord Voldemort. Voldemort kills Cedric and uses Harry’s blood to regain a physical body, though Harry narrowly escapes back to Hogwarts to warn the wizarding world.
