World Champion Jack Blakemore and Alex Cavelli, and Italian Prince, are among those who move about Europe from one famous race to another. Cavelli, the aristocratic challenger, courts danger and thrills, but also wins races. Is he courting destruction or not? Blakemore races with the knowledge that the most acute danger - and the most intense pleasure - is payable by death. And Elizabeth Ashford, an American girl on her first trip to Europe, is smitten by both men, but is too young, too naïve to grasp the terrible stakes for which they play. Elizabeth may be their prize, but life is their only triumph.
