Once again Psychopathic Serge Storms and Lenny, his marijuana smoking sidekick, are back again in another of Dorsey's screwball crime-spree novels. This time they are on the trail of a stash of gems missing since 1964. Serge has escaped from the state psychiatric hospital in Chattahoochee, Florida's and hits the road to Miami. He is obsessed with the idea of clearing up the mystery surrounding his grandfather's alleged suicide as well as finding the legendary dozen diamonds missing since the Murph the Surf's 1964 jewel heist from the Museum of Natural History.
Serge's crusade gets off to a bad start when an altercation with a mob boss stirs the renewed interest of both the mob and the Feds in the 1964 jewel heist. As a means toward finding the jewels and generating much needed funds, Serge starts a specialty Miami tour service. His first booking is a group of drunken salesmen who, out to play a practical joke on a colleague, mistakenly kidnap a mobster. This sets off a series of hair-raising adventures as well as several murders at the hands of other mobsters. Flashbacks from Miami Beach in the 1960s are inserted in between events in the present as Serge tracks his grandfather's movements at the time of the infamous gem heist.
