Complete story — includes the ending
Holt assigns a serial killer case to Jake and Charles and tries to have them avoid using Commissioner John Kelly's new app that allows residents to send in anonymous tips. Terry finds out that he's being transferred to Staten Island since the precinct doesn't have enough money to keep him on as a Lieutenant, so he tries to convince a coworker to quit his job and become a Broadway star. While Kelly's app does help Jake, Charles, and Holt find the killer, they discover that the anonymous tip was sent by one of his subordinates and that he is wiretapping the population. Due to his higher ranking and evidence of Holt texting Jake about bringing Kelly down, they are unable to report his illegal activity.
