Calaboose Cal is driving through a neighborhood where he spots Tom and Jerry doing their usual chase around the yard. He stops the duo and, in his infomercial line of dialog, lets them know that he wants them for his television show, Midnight Kitty Cat Movie Show. Tom and Jerry are not interested and try to run away, but Cal will not hear or let them say no. However, they reluctantly agree when money is presented to them at the studio. Cal tells them to do their thing when the camera is rolling live, but Tom wants his money first. Jerry is annoyed that Tom won't give him the share of the money and pulls Tom's tail which starts the chase before Cal wants them to. Tom and Jerry proceed to do some damage on the sound stage. Cal gets on camera and spouts a number of movie titles for his late night movie show all the while pitching for his Calaboose Cat Exterminator service. Tom is chasing Jerry through a living room set where Jerry out paces him and Cal demonstrates his kitty-pult on the tired out Tom. Cal goes back to introduce the next lengthy movie title and cat themed actors' names while Tom recovers from the kitty-pult and chases Jerry around the set again. This is then followed by another pitch from Cal about Tom being a tired kitty and the solution to solving every ones mouse problem is Cal's mouse-whistle that is sure to be a boom box in the ear of any mouse. However, when Cal uses the whistle it attracts a pack of dogs crashing into the studio. Cal manages to get the dogs out of his studio while, again, Jerry outwits Tom and escapes. When Tom corners Jerry in a mouse hole, Cal shows up with another one of his products, but as per usual, Jerry turns the tables on the two cats using Cal's rotor-rodent in an attempt to shred them. Finally, Cal introduces the Super Stealth Mouse Mangler which Tom activates and it promptly disintegrates and Cal again pitches the phone lines where at this point no one has called and the operators are sleeping. After each chase Cal seems to introduce a new movie title and string of cat named movie stars. For the last Cal product, as Tom is chasing Jerry across the stage, a Boom Boom Boomerang with two sticks of dynamite. The product backfires and explodes on Tom and Cal which results in the studio finally starting to cave in on itself as the three wave goodbye.
