Beverly Hills Cop II

Captain Andrew Bogomil and his detectives Billy Rosewood and John Taggart are investigating a series of robberies known as the "Alphabet Crimes." The perpetrators leave monogrammed envelopes with an alphabetical sequence at the scene of each crime.

Chief Harold Lutz is incompetent and verbally abusive, and he puts pressure on Bogomil to solve the case quickly. When Rosewood calls the FBI to help, Lutz suspends Bogomil and assigns Rosewood and Taggart to traffic duty.

On his way home, Bogomil is shot by Karla Fry, the enforcer of Maxwell Dent, the mastermind behind the Alphabet Crimes. Axel Foley, a detective from Detroit, flies to Beverly Hills to help Taggart and Rosewood investigate the shooting.

Axel poses as an undercover FBI agent and discovers that Dent is robbing his own businesses in order to finance firearms transactions with an arms dealer named Nikos Thomopolis. Axel also learns that Dent is planning to leave the country.

Axel, Taggart, and Rosewood arrive at Dent's racetrack too late to prevent a robbery, but they find evidence that leads them to Dent's oil field, where he is making his final arms deal with Thomopolis.

A shootout ensues, and Axel kills Dent. Karla is killed by Taggart. The police arrive and arrest Thomopolis and the remainder of Dent's gang. Lutz is fired for his incompetence, and Bogomil is promoted to Chief of Police.

I have removed some of the less important details from the original summary, such as the names of minor characters and the specific locations of the events. I have also combined some of the sentences to make the text more concise.
