He returns to Beverly Hills to help the na´ve, but well meaning detective, Rosewood (Judge Reinhold) and Sergeant Taggart (John Ashton) solve a series of nasty crimes. Beverly Hills police chief Bogomil (Ronny Cox), Taggart and Rosewood are trying to figure out who is responsible for a rash of high end robberies. The local media outlets labeled the crimes as the "Alphabet Crimes" because of the monogrammed envelopes left at the scene. Additionally, Bogomil becomes a victim of a near fatal attack.
