As "Reveille" sounds on a U.S. Navy battleship approaching shore, sailor Pete Kelly remains asleep. The bosun's mate Hardy tips his hammock over, but before Pete can hit Hardy, Pete's large, dim-witted pal, Husky Stone, who loyally does Pete's work, fights his fights and gives him money, intercedes. When Hardy assigns Pete the task of painting the top of the smoke stack, Pete feigns a dizzy spell, and Husky does the job for him. After black paint from his bucket tips over into the face of the officer inspecting the ship, Pete is ordered to see the captain. Worried that Husky, who is love-struck for a blonde named Myrtle Montrose, will marry her and leave the Navy if he goes ashore alone, Pete sends Husky instead to the captain. When Husky, instead of Pete, is put into the brig, Pete visits Myrtle, who indignantly throws him out. Husky, who has been released after blaming Hardy for the mishap, then arrives. Pete, Husky, Myrtle and her roommate, Gertie Burns, go for a motorboat ride, and the next afternoon, Pete and Myrtle meet to try to exchange a parrot Husky gave her for a puppy. After the parrot repeatedly cries out "mad dog," which causes havoc among the customers in the pet store and animals who escape from their cages, the distraught owner gives Myrtle both the parrot and the puppy if they agree to leave immediately. In the next few days, Myrtle makes excuses to Husky and goes out with Pete. When Gert expresses doubts that Pete is the marrying kind, Myrtle baits Pete by showing him an ad for an engagement ring and saying that it is just like the one Husky is going to give her. When Pete objects, she embraces him in front of Gert and tells her they are engaged. One night at a dance hall, Hardy cuts in on Pete and Myrtle and tells her that Pete has been romancing her only to keep Husky, his stooge, away from her. Husky arrives and, seeing Hardy with Myrtle, knocks him out. When Myrtle tells him about Pete, Husky punches him, while Myrtle breaks a vase over his head. The fleet leaves for bombing exercises with Husky not speaking to Pete. As they repair the hull of a ship being used for target practice, Husky is hit on the head by a wooden beam and knocked out. After the bombing resumes, Pete realizes that Husky has been left on the hull and swims to rescue him just before the boat explodes. In the hospital, Husky, still not speaking to Pete, receives a package containing the parrot with a note from Myrtle, who is now married. As the parrot recites the names of all of Myrtle's ex-boyfriends, the two friends laugh.
