-The gang goes on an adventure in pursuit of the buried fortune of Greendale's founder, Dean Russell Borchert (Chris Elliott).
-But Richie and Carl, the school board's evil henchmen--alongside a newly re-eviled Chang--are hot on their trail.
-The gang travel to Borchert's old sealed computer lab, where they find that Borchert is still alive.
-He's been down there for decades, in love with a robot, and sitting on millions of dollars.
-The school board thugs attempt to foil their plan and trap the gang by erasing Borchert's robot's memory.
-Jeff is able to reboot the robot by summoning up a happy memory of Annie.
-The gang arrive just as Greendale is about to be handed over to Subway.
-Since Borchert is the school's founder, he must be consulted on its sale, and so the Subway sale is a breach of contract.
-Jeff and Britta call off their plans for marriage.
-Chang spends Borchert's fortune on some snazzy diamond teeth.
