Pat Pemberton (Katherine Hepburn) is a first-class athlete, but you’d never know it if she’s playing while her fiance Collier Weld (William Ching) is around. Whenever he’s nearby, he makes her so nervous that she just can’t play as well as she normally would. One day, she and Collier go golfing with Mr. and Mrs. Beminger. Collier is hoping to get Mr. Beminger to make a large donation to Pacific Tech College, so he asks Pat to be Mr. Beminger’s partner and tells her to do her very best so he’ll win. Of course, the pressure makes her a nervous wreck and she doesn’t have a good game. When she gets tired of Mrs. Beminger giving her unsolicited golfing advice, she makes several perfect drives all in a row and storms off. Collier isn’t impressed, but Charles Barry (Jim Backus) sees her real talent and convinces her to enter a tournament.
Pat quickly becomes one of the top players in the tournament and she catches the attention of Mike Conovan (Spencer Tracy) and his assistant Barney Grau (Sammy White). Mike wants to become her manager and when he first approaches her about it, she turns him down. As the tournament continues, she does very well and nearly had it won it until Collier showed up and ruined her concentration. As they get on the train to go home, Pat and Collier get into a fight which makes Pat decide to take Mike up on his offer. After getting to know Pat better, Mike is surprised to learn that she’s actually pretty new to golfing and that she’s even better at tennis.
Under his guidance, she becomes a famous tennis player, but she still can’t play well if Collier is around. When Collier causes her to lose a big match, Mike and Collier get into an argument, but Pat is getting tired of being treated like a piece of property. But despite that, Pat continues training with Mike and they begin to fall in love with each other. When Mike runs into some trouble with some gamblers, Pat helps him out by beating up the gamblers, which makes Mike admit he’s having a hard time dealing with a woman stronger than he is. Collier hasn’t given up on Pat yet, though, and when he accuses her of having an affair with Mike, she lets him believe it. With Collier finally out of the picture, Mike realizes he needs Pat just as much as Pat needs him and together, they’re unstoppable.
Of all the movies Katharine Hepburn made with Spencer Tracy, Pat and Mike was her personal favorite of the bunch and it’s easy to see why. Hepburn was always a very athletic woman and she clearly enjoyed being able to show off her golfing and tennis skills alongside real-life female athletes like Babe Zaharias and Gussie Moran. As always, Hepburn and Tracy were delightful to watch together and Tracy has just as much fun as Mike as Hepburn had as Pat. Simply, it’s just a nice light-but-smart romantic comedy. Even if you’re not a big fan of sports, Pat and Mike is still extremely enjoyable. If I were to rank my favorite Tracy/Hepburn movies, I’d say Pat and Mike is my second favorite, right behind Adam’s Rib.
