We see signs on a fence that say, "Keep Out," "No Tresspassing," "No Fishing," and "Beware Of The Dog." The latter is the familiar "Spike," the big bulldog who sometimes gets into it with Tom.
Anyway, forget the dog and the signs: Tom wants to go fishing. He gets by the big dog - but not without some tense and funny moments - and sits on the dock and opens his tackle box. Under the heading of "live bait," is Jerry, asleep under his blanket. Tom picks him, of course, and Jerry - dresses as bait with a feathered skirt - is dangled in the water. However, that water is too cold for our "bait," so Jerry scampers back up the pole and back into bed.
Pictured after that are Tom's fishing exploits and his battles not only with Jerry but with a huge barracuda-like fish and, back again with Spike. The most vicious of the three is the fish. Overall, this is very entertaining from the get-go and it has an appropriate ending.
