The Dukes of Hazzard (1979)

Season 4: Episode 20

Rosco has kept a diary detailing Boss Hogg's illegal schemes carried out over the years. Two of Boss' former (and now disgruntled) associates become aware of this and swipe the diary, demanding a huge ransom or else they tip off the authorities. This leaves Bo and Luke with a moral dilemma: Defeat the crooks, as their criminal activities are more serious than Boss'; or see their longtime enemy brought to justice once and for all.
