Dastardly is ready to stop Yankee Doodle Pigeon until he realizes Klunk is the only one following him. They come back to wonder why Muttley wasn't following them (There's no surprise about Zilly). Zilly explains that Muttley's medal is gone. Muttley wants to find the medal but Dastardly insists on catching the pigeon first. Always trying to find an excuse to avoid going into action, Zilly volunteers to stay in the hangar looking for the missing medal but Dastardly says all four pilots are needed for the plan for Operation Prefab. The plan seemed to be a success until Muttley starts asking for another medal. Muttley gets the medal but ruins the plan. Muttley gets really angry at Zilly for doubting it was a good idea to place the new medal in the same place the last one was kept before disappearing. The squadron implements another plan that also fails. When they come back the new medal was also gone leaving Muttley so upset Dastardly gave him his last one. After that they prepare Muttley for the next plan. Muttley would be kept in the air with a balloon while the other would force Yankee Doodle Pigeon to approach him. Whenever it happens Muttley would try to hit the pigeon with a hammer. Zilly was the first one to drive the pigeon to Muttley, who misses his target and hits Zilly away from his plane. Zilly holds Dastardly's plane to avoid falling. Klunk makes his try, with the same results obtained by Zilly. Believing that if he wants something done right he must do it himself, Dastardly forces the pigeon to yet again fly close to Muttley, who misses the pigeon and hits Dastardly's plane's wings, forcing it to crash. Muttley places his new medal in his medal shelf making Zilly remind him that was Dastardly's last medal. Muttley reveals the medal is tied to the shelf via a long string. They then start this day's last attempt to catch Yankee Doodle Pigeon. A trampoline is tied to Muttley's, Klunk's and Zilly's planes while Dastardly jumped on it hoping to catch the pigeon. When the pigeon changes his route the squadron, Due to Dastardly having ordered them to keep the trampoline under it, changes routes too, causing Dastardly to fall. He orders Muttley to do something but Muttley asks a medal in return. Dastardly reminds him he no longer has medals but promises to help Muttley to find his missing ones if he saves him. Muttley agrees and saves Dastardly. After fulfilling his last assignment Yankee Doodle Pigeon goes home. Coming back to his room, Muttley is upset that his last medal is also missing. Being good to his word, Dastardly helps Muttley and both of them follow the string Muttley left attached to his last medal. They follow it to a hole and find a mouse with the medals. They chase the mouse around the hangar only stopping (the mouse also stopped) when Dastardly's phone rings. The General asks for the pigeon and Dastardly says that before catching him they must catch a mouse that steals medals and the chase goes on. Klunk and Zilly laugh.
