At night, on a balcony or patio with a metal railing, a firework explodes in the air above the viewer. A wooden trellis with bare branches stretches across the top of the frame. In the distance below, a few lights suggest a town or city. The sky is a dull grey, obscuring details. After the firework explodes, the scene returns to its initial state.
