Hungry chipmunks Chip and Dale are down to their last acorn.

Chip and Dale are starving in their tree home when they notice a plentiful supply of acorns on an island in a lake. To get to the island, they borrow a miniature model ship of Donald's to sail on. The irate Donald, however, doesn't appreciate them stealing his ship and makes several attempts to get it back and thwart their scheme to get to their acorn paradise. Chip and Dale are, of course, always one step ahead of Donald.
