Mystery. Parties. Scandal. Corruption. Season 4 is going be the most explosive one yet. Spring breakers are getting murdered in Neptune. After Mars Investigations is hired by the family of one of the victims to find their son’s killer, Veronica is drawn into an epic mystery that pits the enclave’s wealthy elites, who would rather put an end to the month-long bacchanalia, against a working class that relies on the cash influx that comes with being the West Coast’s answer to Daytona Beach.
