Tom pursues Jerry through a cellar, but the mouse successfully dives into his mousehole. Tom peers into the hole, and Jerry launches a tomato from a mousetrap into his face. Jerry then climbs up the wall and grabs a handful of eggs from a carton marked "Hen-Grenades". As Tom wipes the tomato off his face, he is promptly covered in egg, with one hit to the eye leaving the effect of him wearing a monocle. Jerry shoots off the corks from a champagne case, knocking Tom into a tub of water with only a pot to keep him afloat. The mouse promptly launches a brick from a spatula, sinking both the pot and Tom. Leading to the 1st war communiqué message, it reads "Sighted cat – sank same. Signed, Lt. Jerry Mouse."
