Paul Kemp (Johnny Depp) is an aspiring author who hasn't been able to sell a book. Instead, he applies for a job at a newspaper in San Juan, Puerto Rico. He gets the job and meets Sala (Michael Rispoli), who gets him acclimated and tells him he thinks the newspaper will fold soon. Kemp is given the horoscope section. He's staying at a hotel and meets Chenault (Amber Heard), who's avoiding a Union Carbide party there. Kemp is immediately smitten with her.Kemp is an alcoholic and his boss Lotterman (Richard Jenkins) tells him to stop drinking. Kemp also meets Moberg (Giovanni Ribisi), a deadbeat who can't be fired.

Chenault is Sanderson's fiancee, but pretends not to know him.Kemp moves in with Sala, who also rooms with Moberg. The place is horribly unkempt and poor. Sala keeps cockerels for cockfighting. Kemp begins to see the poverty of San Juan, but his boss doesn't want him to write about it, as it's bad for tourism. Moberg returns with leftover filters from a rum plant containing high-proof alcohol. Moberg has been fired, and wants to kill Lotterman. He also likes Nazi records.Kemp visits Sanderson and spies him making love to Chenault. He meets Zimburger (Bill Smitrovich) and Segarra (Amaury Nolasco), who want him to help with a real estate scam. Sanderson yells at some locals who are walking onto his beach. Later, Sala and Kemp are driving, and the locals attack them. The police arrive and break up the fight, then throw Sala and Kemp in jail.
