A night in May 1931, Arnold and his colleagues prepare prisoner Dick Franklin for his execution in the electric chair. They bring him to the execution, where several people are sitting and waiting for the death of Dick. Guards Harry and Alex put Dick on the chair and Paul orders the executioner to switch the lever. Dick is electrocuted.

The next day, Harry and Arnold bring in Larry, the new prisoner, and walk him to his cell. Later, Brutus and Arnold go check on the prisoners and they talk about the execution of Dick. When they pass a cell, a black prisoner begs for more food. Arnold spits in the prisoner's face and walks off. Brutus tells him that they don't treat prisoners like that, on which Arnold starts to yell at his colleague and draws his gun at the prisoner.

Brutus asks Arnold to put his gun down, but Arnold pulls the trigger and shoots Samuel in his leg. He explains to his fellow guards that the convicts don't deserve to be treated well fot what they've done. Paul comes out of his office and angrily sends Arnold outside. Harry calls a doctor.

That evening, Arnold phones Paul and tells him that he got transferred to another cellblock where he has no contact with the prisoners. Arnold promises Paul to take revenge on him for that...
