Shoe salesman Harry Witherspoon lives a luckless life, toiling in obscurity, until an unexpected telegram turns his life around: a long-lost uncle has died suddenly, leaving Harry $6 million! There's just one catch: Harry has to bring Uncle Tony on the luxurious Monte Carlo vacation that he never got to take when he was alive!
Harry and Uncle Tony aren't the only ones headed to Monte Carlo, though - they cross paths with dog-lover Annabelle Glick, Tony's mistress Rita and her brother Vinnie, all of whom are trying to claim the inheritance for themselves. An assortment of other colorful characters - including a mysterious Italian stranger, Luigi - pop in and out as Harry and Tony wheel from one adventure to the next.
It's a wacky cross between Weekend at Bernie's and To Catch a Thief, with music from Flaherty and Ahrens, the team behind Ragtime, Seussical, and other Broadway favorites.
