Mr. and Mrs. Jones, a suburban couple, are puzzled by mysterious piano music in their home, long after their daughter's toy piano vanished. A mouse strikes a deal with their cat, promising a piano performance in exchange for his life. The cat hides the mouse and toy piano in a real piano, deceiving the Joneses. Media frenzy ensues, with scientists baffled by the cat's musical talent. Contracts are signed for public performances, culminating in a disastrous show at Carnegie Hall. Exposed as a fraud, the cat and mouse revert to their usual antics until they bond over jazz music. The Joneses keep their unconventional pets a secret.
