Impossible

In a dimly lit, blue-toned corridor, a man in a black leather jacket stands behind two young girls, holding a gun to the back of the girl in the center, while the girl on the left looks on with concern; the scene cuts to a close-up of a man with a shocked expression behind a chain-link fence. The sequence then shifts to a small, fluffy brown dog standing behind a white baby gate, looking through it, before walking forward and approaching the camera.
