Two adventurous retired couples are on extended vacations when they find themselves being chased by murderous thugs. The couples had met in an alternative existence and, along with a relative, had disrupted a secret government operation designed to do away with anti-administration talk show hosts. When the couples meet again, they discover the government must eliminate Cousin Ralph before he broadcasts information about other such operations, and they set out to warn him. But he's vanished --- off on a new crusade to find the "real" Evangeline in Louisiana's Acadiana and Nova Scotia's Acadia.
