The stooges are the 'Minute Menders', three tinkers who live under their car. The boys decide to drum up some business by punching holes in the unattended lunch boxes of some workmen. When they're caught in the act, they escape and accidentally get hired as riveters on a new building, working on the 97th floor. Their ineptitude and lousy workmanship screw up construction of the building and they must parachute off the building to escape the wrath of the boss. The Stooges secure construction jobs on a new building, but find they have to start on the 97th story! (thetvdb.com)
