Mickey, Donald, and Goofy run a locksmith business in their apartment. Mickey gets a call from Minnie telling him about an emergency. The trio tries to get out, but they find that their key is missing. Goofy tries to check his keychain, but only manages to rattle off some lame puns. Goofy then takes out the spare key hidden under his mouth, but he and Donald fight over it and it falls through the door's mail slot. The three try to reel it back in through the window above the door and end up causing trouble for various people in the city and catch a big fish.
