Okay. Following the whole deal about data mining in the last episode, Gryzzl is determined to push ahead and buy the Newport land. They increase their bid. Leslie and the others had a plan to try and get Gryzzl to buy half the land and donate the rest, but they are too late - the Newports accept the $125 million offer.
Leslie and the others all go to JJ's Diner to commiserate over the loss of their goal. Turns out, JJ's is closing down. The lease on the location was purchased by Dennis Feinstein. Andy, posing as Johnathan Karate (Johnny Karate's serious older brother), tries to talk to Dennis about the deal, while Leslie, Ron, etc. host a rally to try and save JJ's. All is for naught, however. Dennis is determined to tear JJ's down.
The next idea is to move JJ's to a new location - in the old, rundown part of Pawnee where Andy and April are moving. The owner of JJ's says that it will never work to have his restaurant in this area, because there is no real commercial activity and he wouldn't be able to sustain his business.
Suddenly, all of these different problems coalesce into one single solution. Leslie and the others convince Gryzzl that they should build their new headquarters in this rundown area, because they would save tons of money on buildings and plumbing, etc. That would turn the area into a thriving capitalist spot, which would make it a viable location for JJ's Diner. At the same time, Leslie convinces Gryzzl to donate the Newport land to the National Parks Department, in order to get back public approval in Pawnee, after their bad decisions with data mining.
