Revenge and Remorse (The Guilty Alibi) - Plot

Plot

The episode starts in the courthouse, at night. A person (of which only his feet are visible) enters. He moves up to room 112, the room of Judge J. Oliver Maxwell. He replaces the normal gavel with a different gavel. When Maxwell uses it the next day, at a hearing, it explodes, killing the judge.

Then we see the main character, Lieutenant Frank Drebin driving in his car, going to the headquarters. After both have decided what to have for lunch, his colleague, Captain Ed Hocken, also tells Frank that seven recently released criminals were sent to prison by Judge Maxwell himself, making this a possible revenge kill. One of the bad guys is Eddie Casales, a bomber that was arrested seven years ago. Ed and Frank decide to pay Eddie's ex wife, Lana Casales, a visit. Lana hasn't spoken to her husband since the two divorced, but he hangs around Club Flamingo a lot, with a chorus girl named Mimi Du Jour.

That evening, Frank and Ed go to club flamingo to ask Du Jour some questions. She tells them that last night, during the courthouse bombing, Eddie was with her, at the movies to see On The Waterfront. While questioning Mimi, Eddie walks in, his alibi doesn't checking with Mimi's alibi, and Frank and Ed eventually leave. The next afternoon, Drebin goes to the lab, to see what Ted Olson has come up with. The latter tells that the bomb that was used to bomb the courthouse was made from seven common household chemicals, which means that anyone with a high school knowledge of chemistry could have made the bomb, ruling out the work of a professional. Also there, Frank displays some restlessness, so Ted gives him some decaffeinated coffee, one of his new inventions. Later that day Frank comes back into the lab, in a more creepy than happy mood, creating some accidents and promptly leaving. Then we see a car in the night, as the same person who placed the gavel-bomb at the courthouse now setting a bomb in a car somewhere. The next morning a man in a black suit steps in to the car and, as soon as the ignition is started, his car explodes.
