Ace Ventura Jr.: Pet Detective

Ventura must follow in his father's (Ace Ventura's) footsteps to save his mother from going to jail.

In the beginning, Ace is chasing a rat that is referred to as a mouse. He catches it and walks straight into the alligator habitat. Later in a dream Ace sees a panda, Ting Tang, being captured. Soon his mother is blamed for the theft. She asks if she can make one phone call. She calls Rex Ventura, Ace's paternal grandfather, but not before a hilarious scene in which Ace Sr. exits from a Rhino. Rex tells Ace (Jr.) the history of the Ventura Family and their relationship with animals. Rex Ventura is an elderly man with several animals such as a cat, a turtle, and a dog which Ace thinks is dead, but springs to life at the phrase "cream pie."

At his mother's trial, Ace Jr. presents evidence that proves his mother couldn't have committed the crime of stealing Ting-Tang the panda; however, the Ranger (the one that Ace doesn't like), dismisses the evidence and Ace's mother is ultimately taken to jail.

At school the next day, Ace hears that the pets of many of his classmates (including his crush, Laura) have gone missing. After that, Ace talks to a boy nicknamed A-Plus (who is called this in jest, as the school recognizes no grade above an A). A-Plus has a hidden lab in his locker, which Ace uses as his office. Ace, Laura, and A-Plus work together to find the culprit, and they initially assume that an animal scientist named Dr. Sickinger is the panda thief, primarily because he had created a website called PandaHub. However, the (somewhat insane) scientist is ultimately proven innocent and ends up working the kids to find the real culprit. While working with Dr. Sickinger, Ace and his friends discover that he used to work for Quenton Pennington Jr. (Reed Alexander), a rich kid whose family motto is, "What a Pennington wants, a Pennington gets." In the end, Ace and his crew discover Pennington Jr.'s dad, Pennington Sr., had stolen Ting Tang, as well as a bunch of other famous animals (Tabby the tabby cat, Princess the lapdog, Freedom the Hawk and Calypso the Magic Horse), and Pennington Jr. himself had stolen Ace's classmates' pets. The father and son are arrested for their crimes, Mrs. Ventura is finally cleared and Ace is rewarded for his heroics.

Ace's father does not appear in this film. Until Rex comes in, whenever Ace Jr. would ask his mom about his dad, she would simply tell him that he had disappeared on a business trip when he was a baby and wouldn't go into any greater detail. However, before she's taken to jail (before Rex comes in), she elaborates on what happened to Ace Sr.: when their son was still just a baby, Ace had rescued a group of endangered animals and while flying them to safety, the airplane they were on disappeared somewhere over the Bermuda Triangle, and Ace Ventura was never seen or heard from again after that.
