When the consciousness of Voldemort (Ralph Fiennes) is connected again, Harry Potter (Daniel Radcliffe) concludes that the last Horcrux is hidden in Hogwarts, so he returns to the cloudy school with Ron (Rupert Grint) and Hermione (Emma Watson). With the help of their friends, they successfully expelled Snape (Alan Rickman), but Voldemort, who noticed Harry's intention, led his disciples to approach Hogwarts. Death Eaters, Dementors, and Giants madly poured into this magic school with a long history, and the decisive battle between good and evil broke out immediately. For a time, there was a bloody storm and countless casualties. From Snape's tears, Harry not only learned the story of his father, but also confirmed the last secret hidden in his body. After that, he and Voldemort ushered in the final duel... This film is adapted from the original work of the same name by the British writer J.K. Rowling, and is also the final chapter of the "Harry Potter" series.
