The inheritance of a condominium in New York, along with a considerable amount of money, brings Betty and Jenny Carr from the small town of Carrsville, Missouri, to the glamorous big city. Betty, the younger of the two sisters, has dreams of becoming a famous dancer. Their sole contact in New York is their unsavory cousin, Colin. Soon Betty takes up with Colin's equally dubious friend, the sleekly sophisticated, middle-aged Antonio Braselmo. Jenny knows little of Betty's affair with Antonio, nor that after months of rejection and disappointment in the theater, Betty has gambled her half of the inheritance on a show that folds after only one performance. Shortly thereafter, Betty disappears, and with only a terse poscard from London as a clue to her whereabouts, Jenny takes off across the Atlantic in search of her sister. There she meets the attractive, sardonic journalist, Mike Baker. From him she learns that Braselmo is a notorious, throughly unscrupulous trafficker in anything that makes money. If Betty is with him, she is in very grave danger indeed. Mike joins Jenny in her desperate search, which leads to a confrontation that is as bizarre as it is deadly. Set in Manhattan, London, Paris, and a mansion high in the Swiss Alps.
