Now much smarter, Tom works at a chalkboard full of equations and invents the atomic bomb. Then Tom is on a ship at sea witnessing a test of the bomb and is awed (and stricken with guilt) when he realizes the bomb's destructive power. A guilt-ridden Tom then invents a time machine and goes back in time with the intention of preventing himself from inventing the atomic bomb. Jerry finds the time machine Tom built early that was too small for the cat. When Tom arrives in the past, he sees himself standing at the chalkboard and approaches his past self.

Having succeeded stop the atomic bomb invented, Tom activates the time machine and emerges where "Most Wanted Cat" takes place. When he sees himself tired of past-Jerry toying with him, he stops himself from leaving the house and having his owner calls pest control, however, as he throws past-Tom's packing bag to the floor, he notices that the bag is packed with a firecrackers, placed as a trap by future-Jerry.

Jerry listens outside the explosion at Toms' faces, waking past-Tom's owner up. The last sound was heard and Tom's past self was fired. Future-Tom watches as past-Tom gets kicked out of the house and then he sees Jerry planning to undo Tom's triumphs. Jerry arrives in a building where "The Million Dollar Cat" takes place. Past-Tom is chasing Past-Jerry and Future-Jerry stops by bringing the bill: $100,000. When Tom sees the bill, he screams and runs straight out through the wall leaving a Tom-shaped hole. Jerry time-travels back to "Jerry's Diary" and fights and beats Tom offscreen for reading his diary, after this, Tom drones "Don't you believe it!".

They switch the points, so the train speeds past them harmlessly.
