Inside a brightly lit indoor ice rink, a hockey practice is underway. A group of young children, dressed in full hockey gear and helmets, skate around the ice, some dribbling pucks with their hockey sticks. Several black pucks are scattered across the ice surface. The rink is surrounded by boards and a spectator area, with a large screen displaying advertisements on one side. The high ceiling is supported by a complex steel truss structure, and numerous lights illuminate the space. An adult in dark clothing appears to be supervising the practice.
