Plot summary
While being shadowed by Clara (the widow from episode 26), Lightman must question an injured officer who can't speak or move after being injured in the line of duty. An investigation reveals that the Chief Police Officer and four other officers were running a dirty rental business in order to make 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 threaten Cal by trying to frame Emily for carrying a sufficient amount of cocaine for selling purposes. Cal is able to solve the investigation, resulting in life sentences in prison for the dirty cops. Meanwhile, the Lightman Group faces a financial crisis, but is rescued by an investment from an equity firm of which Clara is the major investor.
