The 99th Precinct welcomes a new strict commander, Captain Raymond Holt, unlike the previous captain. This causes dismay for talented but carefree Detective Jake Peralta but satisfaction for Detective Amy Santiago. Holt gets to know his detectives, including the dedicated but emotionally unstable Sergeant Terry Jeffords. Meanwhile, committed but not physically gifted Detective Charles Boyle wants to ask the tough Detective Rosa Diaz on a date but needs help from the sarcastic administrator Gina Linetti and Jake Peralta.
