Superb physical specimen and independently wealthy Englishman Kirk Winfield lives the bohemian life of an aspiring painter in New York, sparring with his prizefighting friend Steve and daubing at canvases, until his life is upended by a chance encounter with Lora Delane Porter, an autocratic author of books on eugenics and hygiene. She determines at once that he will marry her niece Ruth Bannister, the daughter of a Wall Street business magnate, and that their child will be raised according to her own unsparing principles. When their son Bill arrives, Kirk and Ruth must discover a way to navigate their new life together against the currents of her family’s wealth, his artistic aspirations, and Lora’s meddling.
