Vaudeville team Olsen and Johnson arrive in New York hoping to land a job at the Eldridge Theater for their singing seal Sally, but they find that the theater has been deserted since a murder occurred there two years earlier. Joan Eldridge, who recently inherited the theater, wants to open it, but William Bailey, who has loaned her money and whom she thinks is a friend, tries to convince her to sell. When a rumor spreads that Olsen and Johnson are two oil millionaires who will back the show, Bailey, who is trying to get control of the theater for investor Pete Phillips, learns that the vaudevillians, far from being millionaires, left the last town in which they performed owing everybody money. At the suggestion of Don Fletcher, Sally’s pianist to whom Joan has become attracted, the company decides to put on the show without salaries, but during the dress rehearsal, Bailey, who is enjoying the acts, is shot. Olsen and Johnson think Sally did it and hide the gun she uses in her act in her fish bucket. When they find the fish gone and the bucket empty, they take Sally, with police inspector Murphy, on a roller coaster hoping that she will regurgitate the gun. Sally, however, loves the ride, while the men become woozy. Later, Sally’s gun, which is found in the theater, is discovered to be the wrong calibre. Olsen and Johnson convince MacDougal, owner of MacDougal’s Mackerel, to sponsor a radio broadcast at the theater during which they promise to reveal the murderer’s name, which they don’t know. They are kidnapped by Phillips’ thugs and are going to be murdered, but Sally knocks one on the head with a bowling ball, and Olsen and Johnson escape. At the theater, Phillips shoots at them, but he is chased and apprehended as Olsen provides the radio audience with a play-by-play description. More on Wikipedia or Mubi
