Harry Potter and the Chamber of Secrets — summer holidays. After 1 year of study at Hogwarts School of Witchcraft and Wizardry, Harry is once again forced to live with the Dursley relatives. He had not received letters from his friends Ron and Hermione for a long time, despite their promise to write.
On Harry's 12th birthday, Uncle Vernon (not remembering the holiday date) receives guests, potential business partners. He tells Harry to sit quietly in his room, not to show himself to the newcomers. Suddenly, a strange creature appears in the room, introducing itself as Dobby the house elf and warning him that he will be in mortal danger if he returns to Hogwarts. Dobby admits that he stole his friends' letters because he did not want to put Harry in danger. Harry insists that he will return to Hogwarts, causing Dobby to cause a commotion in the house, ruining the reception.
