Bad rabbit

A rabbit in a police uniform speaks with a concerned expression, then smiles and gestures with her hands, before the scene cuts to a group of knights in armor crouching behind rocks on a hillside, then a close-up of a knight's helmet slicing into a white rabbit's head, followed by a figure in a white robe with a red hood walking into a dark cave entrance surrounded by bones, and finally returning to the knights on the hillside.
