The Major Case Squad investigate the murder-suicide of a city auditor who appears to have killed his family and then himself; however, an analysis of the crime scene suggests a different scenario. When Goren and Eames learn that the dead man uncovered a pensions scandal involving retired police officers, the trail leads them to corruption within the force. When the dead accountant's report of the city school district's School Security Division is discovered, the detectives learn that he was investigating the illegal practice of retired cops drawing a city pension while also drawing a second NYC salary as School Division officers. Evidence of the murders points towards a handful of former cops, particularly a tough female School officer with an urgent need for money to keep her daughters in an expensive private school.
