Not mine

Three women in matching black t-shirts run across a gymnasium, each holding a red dodgeball, as the camera follows their forward movement. The scene cuts to a woman in a white suit walking down a school hallway, then turning to pose with her hands on the wall, while two men watch from the foreground. The sequence continues with a woman in a nurse costume holding a teddy bear, followed by a woman in a vintage-style dress with her hands raised, and ends with a close-up of a woman singing.
