The Cerritos is headed to Starbase 25 for the annual Command Conference (which is purported to have one of the most outrageous after-parties in the quadrant!) and it will be the only California-class ship attending. Captain Freeman is rather chuffed.
There's just the problem of the Doopler Ambassador who gets to "dooplercating" himself when he gets insulted and results in the ship having to be locked down until he can stop multiplying.
Mariner and Boimler take advantage of the chaos to sneak aboard the station and attend the party on their own. Things go promptly south when they run into one of Mariner's old "associates."
Meanwhile, Tendi and Rutherford just want to complete their Cerritos miniature model. Well, Rutherford *really* wants to complete it – but all those dang Dooplers are getting in the way!
