A bungling gumshoe tries hard to affect a hard-boiled demeanor, despite the fact that his latest assignment is to protect the bratty young heiress to a fortune in this lively spoof of detective movies. Henry Brilliant, Private Eye, is no stranger to the ways of the wealthy as he too comes from a blue-blooded family, but he tries to ignore that to become the classic Chandleresque detective as he heads for Europe to follow the girl on her tour and keep her from being kidnapped by her stepmother who is really after her husband's secret formula for controlling the weather.
