Teacher and Pupils

While investigating the murder of a police officer, Cal discovers a conspiracy that could threaten his daughter. Meanwhile, Cal must get the Lightman Group out from under a financial crisis. Lightman is put to the test when he must question an injured officer who can't speak or move after being injured in the line of duty. While investigating, it was found that the Chief Police Officer and four other officers were running dirty renting business in order to earn more money. This led to the death of a character named Jenkins, as he tried to oppose the dirty business or at least get his own share. The injured officer was able to help Cal identify the four officers, who later threatened Cal by trying to frame Emily for carrying a sufficient amount of cocaine for selling purposes. Once again, Cal is able to solve the investigation, resulting in life sentences in prison for the dirty cops.
