Rich boy Adelbert Wallingford is kidnapped and aspiring detective Mickey decides to crack the case. The gang earns a dollar delivering a package to Mr. Wallingford, which turns out to be a ransom note. He's supposed to attach the money to a pigeon and then let it go. If the pigeon returns without the money, then goodbye to Little Adelbert. Unfortunately, the pigeon escapes before any money can be attached to it. This leads to a daring chase to catch the pigeon, with Mickey, Joe and Farina taking a small plane.
