In a prequel to SWEEPERS: DIE ONCE MORE Dr. Mackenzie Conley, a CIA operative and expert on bioterrorism, is in Morocco undercover as a visiting professor at the University. Her mission is to investigate rumors of a powerful new nerve gas delivery system being perfected somewhere in the area. The rest of her team has already gone home after spending two weeks without finding even a hint of such a weapon. Mac stayed behind to finish her six-week stint to ensure her cover stays intact should she need to use it again.

Jordan McAllister and her quirky friends are celebrating Cinco de Mayo this year at a new casino in Oklahoma, compliments of recent acquaintance—famous New York chef George Christakis. With margaritas flowing and Mexican cuisine piled high, the weekend promises to be one big party. However, Jordan can’t help herself and snoops her way into a scheme involving casino chips. The stakes are raised when the lead singer of the casino band turns up missing and more than one person has motive to want her out of the picture. It’s assumed the high-maintenance woman ran off with the CFO of the casino, especially when it’s revealed they were having a tryst, and that he’s also gone missing.

Jordan McAllister’s brother, Danny, is in deep trouble and has been jailed in Amarillo. After a night on the town at the local cowboy bar, Danny had awakened in a seedy motel room next to a naked woman with a steak knife protruding from her chest. Since Danny’s fingerprints are all over the knife, and his DNA is under her nails, he’s charged with the murder of Carlita Fontaine, a dancer at a local strip club. Now Jordan, along with her quirky friends and new fiancé, Dallas FBI agent Alex Moreland, race to Amarillo to try to find a way to help her brother out of his dire situation.
