Shameless

A man with cornrows walks down a narrow corridor, then the scene cuts to a man in a black shirt confronting another man in a dimly lit room. The sequence continues with a blurry shot of a person falling, followed by a man and a woman in a tense confrontation on a city street. The scene shifts to a man standing in a dark, overcast environment, then cuts to a man at a party with the word "SUCKER!" overlaid in red text.
