Where from

A man in a white lab coat sits at a table in a dimly lit room, looking forward and then turning his head slightly, while another man in a light-colored suit sits across from him, holding a small object and looking toward the man in the coat. The scene cuts to a wider view showing a group of people seated at tables in a classroom-like setting, with the man in the white coat and the man in the suit as the central figures, and the man in the white coat eventually turns his head to look at the man in the suit.
