This wartime film follows a formula that MGM used on quite a few Wallace Beery films. Once again the over-age and over-weight Beery is supposed to be a career military guy. However, the big difference in this film is that his Navy man is with the Lighter Than Air service--balloons that were used for submarine patrols. I can't think of another movie that dealt with this important branch of the Navy--even though 12,000 men served with this service and they were incredibly successful.
Beery plays Ned Trumpet--a guy who is pretty much the same as he played in other films of the genre. He's got a heart of gold but also lies like a rug--and when his friend/rival Jimmy (James Gleason) talks about the exploits of his son, Ned talks all about his as well. The problem is that Ned NEVER was married nor has any kids! So, after meeting a nice young man, Jess (Tom Drake), he decides to unofficially adopt him and begins telling his friends about how great 'his boy' is! What Ned doesn't know is that Jess is disabled and cannot walk--and Ned's plans for Jess following him into the LTA service appear impossible. But, thanks to a nice-guy doctor who thinks he can cure Jess, the man is able to join the service. This only takes us to about midway through the film--what happens next is for you to see for yourself. Rest assured, however, that like most of these other films, it involves redemption and incredible coincidences!
Overall, like all the Beery military films, it's high on propaganda but also on entertainment. Sure, it does follow the formula, but it's well made and enjoyable throughout.
By the way, I read up on this and found that during WWII there was a single case where a blimp that was sunk by a sub. They lost one crew member in the attack. Otherwise, the blimps were incredibly successful and had a huge advantage over the subs and lost hardly a ship during their escort duties.
