Elmer fixes up a room for his just-married, freeloading brother-in-law and wife. When the newlyweds show up, Henry brings a surprise in the form of stepson Junior. The apartment is now too small, so Henry decides that they'll buy a lot and build a do-it-yourself home, a disaster in the making when Junior switches the house's part numbers. It doesn't help matters that Elmer, Henry and the wives are all incompetent.
