Alex Barnaby and Sam Hooker are back together and fighting crime the only way they know how — by leaving a trail of chaos, panic, and disorder. Alex, an auto mechanic and spotter for racecar driver Sam Hooker, is drawn to trouble like a giant palmetto bug to a day-old taco. Unfortunately, she's also drawn to Hooker in the same fashion. There's no steering clear of trouble or Hooker when friends Rosa and Felicia call for help. A man has gone missing, and in order to find him Barnaby and Hooker will have to go deep into the underbelly of Miami and south Florida, surviving Petro Voodoo, explosions, gift- wrapped body parts, a deadly swamp chase, and Hooker's mom.
