To be a Pet Detective, you have to understand both the criminals and animals. Ace Ventura(Jim Carrey) goes even further... He behaves like a criminal animal. He's the best there is. In fact, he's the only one there is! Ace is on the case to find the Miami Dolphins' missing mascot and quarterback Dan Marino. He goes eyeball to eyeball with a man-eating shark, stakes out the Miami Dolphins and woos and wows the ladies. Whether he's undercover, under fire or underwater, he always gets his man . . . or beast!
