Stand and Ollie are hired by a homeowner (Sam Lufkin) to finish building a house for him. Furthermore, they are offered a $500 bonus if they do a speedy job. In typical Laurel and Hardy fashion, they proceed on their appointed task with zeal but experience one disastrous result after another. Compounding their difficulties is a nearby hospital whose small but feisty head nurse sics a policeman (Edgar Kennedy) on the finishers for being too loud in their work. The policeman tries to keep Stan and Ollie as quiet as possible. In doing so, he unwittingly gets in the firing line and suffers numerous indignities, including having a bucket of glue and a stack of shingles fall from the roof onto his head. Eventually the home is finished, and Stan and Ollie seem to have done a passable job. The homeowner arrives. Pleased at what he sees, he gladly pays Stan and Ollie their promised $500 bonus. Moments later, however, a tiny bird lands on the house's chimney. The small creature causes the chimney to collapse and crash through the roof, which weakens the entire structure of the new house. The enraged homeowner demands his $500 back. Stan and Ollie refuse and engage in some creative teamwork to keep the $500 in their hands. A fight breaks out and the hapless policeman, who happens to walk by, is drenched in white paint. The nurse from the hospital--which now sports a sign saying it has been put up for rent--is knocked into a large vat of paint. Eventually, Stan and Ollie's truck rolls backwards into the house, completely wrecking what was left of it.
