John Wayne is a star football player from West Point and after winning the Army-Navy football game with an extra point, he's off to serve with his mentor, the Colonel, in Arizona. However, before leaving, he gives his girlfriend (Laura La Plante) the brush off--telling her he really wasn't serious about her and would not marry anyone...ever. She was crushed and, oddly, makes the moves on the Colonel. After a short courtship, they marry and they, too, are off to Arizona.
Once there, she and Wayne don't tell the Colonel about their prior relationship and Wayne begins dating the lady's younger sister (who, by the way, looks a lot like her). However, it's obvious the old girlfriend carries a grudge and doesn't like her sister hanging around Wayne. Despite earlier in the film saying he didn't want to ever marry, he does fall hard for the sister and they secretly marry.
Not knowing her sister and Wayne are married, Ms. La Plante decides to hurt Wayne and get rid of him once and for all--claiming Wayne tried to sexually assault her!!! However, when she finds out that her sister is married, she tries to change her story but still weasel out of the responsibility for lying--saying she had heard from someone that Wayne was a cad so she made up the story. Finally, though, she convinces her decent husband (the Colonel) that Wayne was innocent and her earlier accusation was fabricated and everyone, apparently, lives happier ever after--though this wasn't spelled out clearly. What ALSO wasn't spelled out clearly but I think was strongly implied, by the way, was that Wayne and La Plante's earlier relationship was sexual--adding deeper understanding for why she behaved so vindictively towards him later.
This was a pretty lousy film all around and aside from the fact it starred John Wayne, I probably never would have watched it. In his early career that spanned almost an entire decade, Wayne was NOT that popular or famous--appearing mostly in westerns made by studios from "poverty row". The term "poverty row" refers to the incredibly low budgets and low production values many of these tiny studios possessed. Most of these films, quite frankly, are pretty poor and just aren't worth wasting your time on unless you are a die-hard John Wayne fan. I actually do, on rare occasions, like to watch one of his "Three Mesquiteers" of "Singing Sandy" series films--they are fun and mindless and it's also fun seeing Wayne in the most ridiculous situations (such as playing a singing cowboy like Gene Autry). A few of his early films were actually NOT westerns and this is an example of a film made by a not-quite-poverty row studio (Columbia--several years before their glory years and bigger budget films).
So why is it so lousy? Well, it isn't all because of the budget, though this didn't help. Much of the film was obviously made inside a sound stage and a lot of stock footage of an Army-Navy football game was recycled. However, what really sunk the film was the amateurish acting and, at times, ridiculous script. No one could act, though one of the worst offenders in this department was John Wayne himself! All the self-assuredness and swagger and energy that you have come to expect from him are gone. Instead, he just seems like a very young and inexperienced actor who could have used more coaching--which is exactly what he was. The positive is that films like this DID help to polish his acting (sort of like putting him in the minor leagues for a few years until he was ready for the big time). The negative is that the film is gosh darn awful--being very silly and sloppily made.
