I'm Batman

A man in a dark jacket stands in a dimly lit room, gesturing with his right hand while speaking to someone off-screen, then the scene cuts to a close-up of a man in a Batman costume with a wet mask, his mouth open in a yell, followed by a cut to a man with blood on his face, bound with duct tape at the waist, sitting in a chair and looking distressed, then back to the Batman figure yelling, and finally back to the bound man with a pained expression.
