Tom heads for a big city penthouse to become acquainted with a rich pretty female cat that lives there. He brings her Jerry as a gift and does some humiliating things to Jerry. Jerry, in turn, attracts the attention of another cat who also becomes interested in the female cat.

As Tom and Jerry stage their typical fight sequences, the patriotic soldier theme of the title is evidenced by such things as a carton of eggs labeled "Hen Grenades"; Jerry dropping light bulbs from an airplane like bombs; and Jerry sending a telegram with the message "Sighted Cat - Sank Same." Musical phrasings from various patriotic war songs are heard throughout.
