Robbers Ace and Scratch are caught in the act of robbing a casino vault and are caught after a long chase by the owner of the casino, who chooses not to send them to jail but instead hires them on as security consultants. The current head of security at the casino is not happy, but casino exec Amber couldn't be happier.

Epicenter concerns brassy, beautiful Amanda Foster, a down-on-her-luck Los Angeles detective who's been assigned to protect a mobster-turned-State's-Witness, Nick Constantine, from the mob. On the night of the assignment, the city is rocked by a devastating earthquake, forcing Amanda and Nick to fight their way through the ravaged city streets while being pursued by ruthless assassins and corrupt cops.
