Matty Matlock

In 1927, a Kansas City, Missouri cornet player and his band perform nightly at a seedy speakeasy until a racketeer tries to extort them in exchange for protection.

A bandleader, desperate to get his band's instruments out of hock, promises the pawnshop clerk--an aspiring songwriter--that he'll let the band's female singer do the clerk's songs at a local club if he will let the band "borrow" their instruments at night. The clerk's girlfriend, however, thinks that the band singer is after more than her boyfriend's songs.
