When Gloria hires a too-good-to-be-true male nanny (guest star Adam DeVine), Jay and Manny are pretty much dead set against it. Frank (guest star Fred Willard) is in town and feeling a bit lonely recently so Phil and Jay take him out to help get his groove back. And, Mitch and Cam commission Pepper (guest star Nathan Lane) to plan their dream wedding but Pepper might be dreaming a little too big.
We flashback to 1990 SBPD. Herb Wilkins, the Chief of Police at the time, is giving then detective, Henry Spencer, a lecture on his mistake on a case. Herb ends up firing Henry off the case and replaces him with SBPD's star detective team, Peters and Boone.
