Pluto chases a
kitten through the forest, a mud puddle, a window, and right into
Mickey's lap, causing a mess in Mickey's house. Mickey angrily scolds Pluto for his mean and nasty behavior towards cats, warning him that he will have "plenty to answer for on [his]
judgement day" if he keeps this up. Mickey then goes off to wash the kitten while Pluto falls asleep in front of the fireplace. While asleep, a
phantom cat goads Pluto into chasing him, over a
hallucinatory Mickey's objections, and Pluto is lured into a forest of evil cat-like trees, and a cat head-shaped mountain trap, where he slides down into a pit, where
shackles magically chain him and he is put on trial as the cats declare him "
Public Enemy No. 1" for all his crimes against cats. All the cats whom Pluto has ever tormented testify against him: a tubby cat speaks of being picked on and chased by Pluto because he (the cat) was fat and was flattened by a
steamroller while running away from Pluto; a psychiatric patient is wheeled out to demonstrate the
post-traumatic stress disorder which he developed from Pluto's barking; and three young
blackface kittens sing of how Pluto stole their meals and drowned their
Uncle Tom (as Tom's
nine ghosts briefly appear) in a river. Pluto is inevitably found guilty and is about to be burned alive by being tied in a seat and lowered into flames by the angry cats, when he wakes up after a hot
cinder from the fireplace strikes his rear. Pluto rushes off into the tub to ease the burn, and Mickey, washing the kitten, urges the two to make up, which each one readily does much to Mickey's delight. ==Voice cast==
