Brooklyn Nine-Nine concludes its season Tuesday night, and, after a surprising turn of events in the squad's attempt to track down Adrian Pimento's (Jason Mantzoukas) hitman, the crew drops everything when they suspect Holt (Andre Braugher) is in danger. Charles ((Andre Braugher) and Amy (Melissa Fumero) meanwhile, get stuck on a flight, and when Amy's anxiety about the well-being of her crew starts to get the best of her, she loses her cool--in first class, no less.

Dennis Haysbert guest stars in the episode as Special Agent Bob Anderson.

Brooklyn Nine-Nine airs Tuesday at 9/8c on Fox.
