As a flashback, Lord Voldemort is shown packing his bags and preparing to leave his house. As he does so, he pauses over a photograph of himself and three other students before abandoning it. In the present, Grisha McLaggen is attempting to break into a Soviet Auror warehouse, but despite defeating many of the guards is captured and fed an intravenous drip of Veritaserum while questioned by General Makarov. In a mixture of flashbacks and present tense a Soviet reconnaissance team finds a chest filled with dark objects, including Tom Riddle's diary, but are killed soon after opening it. In the warehouse Grisha explains that she was a student with Riddle at Hogwarts, who along with Wiglaf Sigurdsson and Lazarus Smith were the true heirs of the Hogwarts founders (Gryffindor, Slytherin, Ravenclaw and Hufflepuff respectively). The heirs formed a club dedicated to "making the world a better place". When an argument occurred between Lazarus and Tom over Grisha's affections, they fell out. Grisha noted that Tom was becoming distant to them all and changed completely after the incident. Over the last few years Grisha has become an Auror and dedicated herself to tracking down Tom in the belief she can save him from himself and the dark path.
