The Extravaganza of the Seas is a 5,000-ton cash cow, a top-heavy tub whose sole function is to carry gamblers three miles from the Florida coast, take their money, then bring them back so they can find more money. Travelling this trip are Fay Benton, a single mom and cocktail waitress, desperate for something to go right for a change; Johnny and the Contusions, a ship's band with so little talent they are, well, the ship's band; Arnold and Phil, two refugees from the Beaux Arts Senior Centre; Lou Tarant, a wide, bald man who has killed nine people, though none recently; and an assortment of uglies with names like Tark and Kaz whose job it is to facilitate the ship's true business, which is money-laundering or drug-smuggling or...something.
