Pat Pemberton (Hepburn) is a brilliant athlete, except when her domineering fiancé is around. The ladies golf championship is in her reach until she gets flustered by his presence at the final holes. He wants them to get married and forget the whole thing, but she cannot give up on herself that easily. She enlists the help of Mike Conovan (Tracy), a slightly shady sports promoter. Together they face mobsters, a jealous boxer (Aldo Ray), and a growing mutual attraction.
