In an effort to keep his business, Hotel de Cocoanuts, from bankruptcy, owner Hammer (Groucho Marx) flatters and cajoles the wealthy Mrs. Potter (Margaret Dumont), his only paying guest. While Mrs. Potter's daughter, Polly (Mary Eaton), has romantic designs on the hotel clerk, Bob (Oscar Shaw), two other guests compete with Hammer for Mrs. Potter's attentions. Meanwhile, brothers Harpo (Harpo Marx) and Chico (Chico Marx) take advantage of Hammer's inattention to wreak havoc around the hotel.
