Musical phrasings from various patriotic war songs are heard throughout.

Donald needs a log for his fire. Unfortunately, the one he picks is occupied by a couple of chipmunks and their stash of acorns. When he cuts it down, Chip and Dale fall out, but their acorns stay behind, so they work at putting out Donald's fire and retrieving their stash. Donald, of course, takes this as calmly and cheerfully as you would expect.

Butch convinces Tom and Jerry that there's no reason to fight and they should all sign a peace treaty. Tom and Butch even rescue their pals from a fellow cat and dog.
