In an alternate timeline 1984, Jamaica's crown jewel is Nu Kingston—a retro futuristic metropolis where gang lords control hordes of zombie-like addicts with a drug called Spice. Worst among them is BadMan Jones, who is prophesied to wipe out humanity for mysterious extraterrestrials. As Spice spreads to every corner of the island, Major Lazer can no longer maintain neutrality and must rely on new weapons and old comrades to prevent total apocalypse.
