Boom

A blonde woman in a white shirt and red boxing gloves throws a punch, her foot lifting off the wooden floor, then the scene cuts to her mid-punch in a boxing ring with a large black boot descending toward her, followed by a close-up of the boot hitting the floor, then a reaction shot of three onlookers with wide eyes, and finally a wider shot showing the woman standing in the ring as the boot looms above her, with spectators watching from the sidelines.
