Robert Armstrong, Edgar Kennedy, and William Cagney are powder mixers. They invent and put together explosives for a company which has just opened a plant in a Latin American company. They are sent down to the new plant, where they play gags on each other, and try to make time with various women, and get into scrapes.
It's a lighthearted trio comedy, a lot like the ones that Warner Brothers made with Jimmy Cagney, Pat O'Brien and Frank McHugh, but definitely low rent, and without the easy camaraderie of the higher-priced assortment that Warners would put together. Armstrong plays his mug character, talking out of the side of his mouth. Cagney is the youngster of the three, and it's up to him to be in love with Marion Burns, the company's secretary who's sent down to the new plant to be liaison with the main office. Kennedy, unsurprisingly, is the surest farceur of the three, even though he doesn't get to do his signature slow burn. Other recognizable names are Wilhelm von Brincken and Gino Corrado.
The copy I looked at had a soundtrack so filled with hisses that it was occasionally difficult to tell what was being said.
