Diner owner Mike Clancy is told by his doctor to get some rest as the Bowery Boys cause general mayhem. Sach (Huntz Hall) tries to help but you know how that goes. A real estate agent and his assistant overhear their conversation and offer a country home for sale. The boys take Mike up to the place but it's a wreck. They try to fix up the place and end up finding hidden loot. The place was formerly owned by a gangster's widow and other gangsters come looking for their money. That's before the ghosts.
It's more of the same from Sach and the Bowery Boys. It's rather late in the franchise and I would think the audience of its time must be getting tired of it all. Aside from some new personnel, this is very much the same old stuff. It's not necessarily good but it's not actually a bad thing. You get what you expect.
