Hogwarts Heat

Three young men in school uniforms stand together in a dimly lit, arched hallway, each drinking from a metal flask; the camera focuses on the boy in the center as he drinks, then cuts to a black-and-white scene of a DJ in a crowded, arched hall, followed by a distorted image of a crowd, then a black-and-white shot of two figures dancing in a large hall, and finally a distorted close-up of a figure with long hair and a beard.
