Columbo is a friendly, verbose, disheveled-looking police detective who is consistently underestimated by his suspects. Despite his unprepossessing appearance and apparent absentmindedness, he shrewdly solves all of his cases and secures all evidence needed for indictment. His formidable eye for detail and meticulously dedicated approach often become clear to the killer only late in the storyline.
The owner of a bull ranch in Mexico gives his workers the day off, and then talks his number one man into fighting the bull who nearly killed his son. But instead he shoots him with a tranquilizer gun, and lets the bull kill him. Colombo, who is on vacation in Mexico, gets dragged into this case by an admiring colleague, but he has trouble convincing the Mexicans that the accident is really homicide. And how do you prove that the bull is a murder weapon?
