It’s the day of Frank and Noelle’s wedding and everyone at 15 Division, especially Andy, is hoping for an easy shift so they can get out early and start celebrating. But those hopes are dashed when Andy and Nick discover a casino-bound bus full of old people who’ve just been robbed at gunpoint. The case gets messier as they realize they may be looking for an “inside man” and will have to re-interview all the seniors involved. Meanwhile, wedding preparations are also getting messy – in fact, the bride seems to have disappeared. Andy and Nick track down and stake out their bad guy, while Traci and Steve Peck find Noelle and try to convince her to tell Frank what’s going on. Andy’s hopes for a perfect day take a different turn when she and Nick wait for the bad guy and share a strangely intimate moment together.
