Grand Nagus Zek, the revered leader of the Ferengi business empire, pays a visit to Quark, who worries that the legendary Ferengi wants to buy his bar out from under him. Instead, Zek plans an important conference at the bar to discuss the future of Ferengi business in the Gamma Quadrant. There, to everyone's surprise, he announces his retirement and selects Quark to replace him! After a few threatening encounters, Grand Nagus Quark quickly learns that great power comes with great danger. When Zek dies, Quark barely avoids an assassination attempt at the funeral. Soon the greedy new Nagus finds himself trapped in a treacherous battle for power — and like a true Ferengi he loves every second of it.
