Eddie Harrington and Albert Mansfield are plumbers who receive a call about a leak in the private bathroom of Mr. Van Cleve, a wealthy businessman.

He winds up inviting her to another gala event, Mrs. Winthrop's estate Briarwood, where a valuable painting, The Plunger (a heavy gambler), is to be unveiled.

Mrs. Van Cleve was intending to send Eddie and Albert a letter of complaint for the devastation that they inflicted on her home.

However, they clear their names when Eddie and Albert, in a fire truck, capture Drexel and Marlow and recover the painting.

Another classic routine at the end of the movie was the throwing of rocks to stop the boys in their tracks at a tremendous distance.

To save time, much of the climactic fire engine chase was lifted from W.C. Fields' Never Give a Sucker an Even Break.
