Based on the debut novel by Hunter S. Thompson, "The Rum Diary" tells the increasingly unhinged story of itinerant journalist Paul Kemp (Johnny Depp). Tiring of the noise and madness of New York and the crushing conventions of late Eisenhower-era America, Kemp travels to the pristine island of Puerto Rico to write for a local newspaper, The San Juan Star, run by downtrodden editor Lotterman (Richard Jenkins). Adopting the rum-soaked life of the island, Paul soon becomes obsessed with Chenault (Amber Heard), the wildly attractive Connecticut-born fianc�e of Sanderson (Aaron Eckhart). Sanderson, a businessman involved in shady property development deals, is one of a growing number of American entrepreneurs who are determined to convert Puerto Rico into a capitalist paradise in service of the wealthy. When Kemp is recruited by Sanderson to write favorably about his latest unsavory scheme, the journalist is presented with a choice: to use his words for the corrupt businessmen's financial benefit, or use them to take the bastards down.
