In the screen, we see a woman lying unconscious or dead on the floor (possibly having been raped or otherwise sexually assaulted as it appears her panties or something else are around her ankles) as a man pours something flammable on her. He then lights some paper and drops it on her (we don't see her burning, but do see the house burning).
A masked man sneaks up on another man at his car at night and repeatedly shoots him at close range. The man tries to get away, but is shot again more times, including while lying beside the car (with the shooter firing beneath the car and hitting him and one tire) and through his hand that he holds up. He then walks up to the man, holds his gun to his head and fires, but our scene then quickly cuts to a flashback of the man's childhood.

A man and the rest of his crew set out to avenge another man being shot and paralyzed. When the others are hesitant, the man takes the gun, walks up to their rivals on a street corner and opens fire, hitting at least one several times before retreating.

Various men attack a man in prison, with a man coming to his rescue. Various punches are thrown and shivs stabbed and sliced at various people. The guards finally show up and beat one guy with their nightsticks, while a man pummels another, but he and the other man are then subdued and cuffed.

We see several dead bodies: one lying on the ground near a car with a bloody gunshot wound in the head, and another wrapped in plastic in the trunk of a car -- two men put it into a garbage truck.

We return to the scene where the masked man sneaks up on a man and shoots him several times. We then see him holding his gun to the man' head, but his aim is off when the man's grandmother yells out. That causes him to shoot through the side of the man's face, severely injuring but not killing him.
A man threatens another man, and they fight: one pushes his thumbs into the other's eyes, they struggle on the floor, one man pulls a knife and lunges toward the other, and he is shot by yet another man (we see him lying on the floor with a bloody wound on his side); then we hear two more shots and see the man dead with a bloody bullet wound in his head. A man stabs a young man three times in the stomach.
