Krazy is at his house reading a magazine. Ignatz comes in and goes inside a jar of jam. Krazy is aware of this, and tries to get the rodent out of the jar. After getting bitten in the paws, he decides to discard the container, along with Ignatz, outdoors. But as he exits the house, Ignatz makes it out of the jar without him realizing. When the cat is gone, the rodent plays the piano for a few moments before going inside the instrument.
