Detective Joe Peters has been accused of taking bribes and murdering a fence, and also suspected in the death of a fellow cop. When it comes right down to it, one of the other cops on the force was more involved than they should have been.

When a prison guard is accused of murder, Matlock actually goes into the prison itself to defend the man.

While Matlock finds the weapon inside the prison, Conrad works on the outside to clear the guard and keep Matlock safe.
