I used Wikipedia to make sure the description was accurate because it's been a little while since I last saw this. http://en.wikipedia.org/wiki/Bullitt
Made in: 1968. I love this movie!!
A politician named Walter Chalmers(Robert Vaughn) is holding a subcommittee hearing on organized crime in America. He hopes to get the message through by trying to bring down Chicago mobster Pete Ross(Vic Tayback) with the help of witness Johnny Ross, his brother. This movie takes place the weekend before the hearing, from Friday to Sunday.
Following the escape from Chicago to San Francisco with $2 million in mob money, Johnny(Felice Orlandi) is placed under protective custody by the San Francisco Police Department and Lt. Frank Bullitt(Steve McQueen) is the officer in charge of protecting him. Him, Sgt. Delgetti(Don Gordon) and Det. Carl Stanton(Carl Reindel) give Ross 24 hour protection at the Hotel Daniels, a cheap hotel and house of prostitution near the Embarcadero Freeway. Late at night on Saturday, a couple of hitmen(Paul George and a stunt driver named Bill Hickman) bust in, shooting up the place, injuring Insp. Stanton and Det. Ross. When news of this hits Bullitt, he wants to investigate who shot them. Meanwhile, Chalmers is upset and tries to shift the blame over to the SFPD, and in the hospital, Ross dies. When Bullitt hears this, he wants Doctor Willard(Georg Stanford Brown) to have the body listed under a John Doe identity.
Chalmers arrives at the hospital and angry Ross is gone. When him and his police officer(Normal Fell) pressure Bullitt to make Ross appear, it doesn't work. Bullitt reconstructs Ross' movements and it leads him to a hotel where he finds a woman registered under the name Dorothy Simmons(Brandy Carroll). He soon begins to suspect the dead mobster is not who he seems, and when he leaves the hotel, he is chased by the 2 hitmen in his Ford Mustang, resulting in one of Hollywood's greatest car chase scenes that kills the hitmen. When he gets back to the police department, he is interrogated and given a message: produce Ross by Monday morning. When he starts to investigate the Dorothy Simmons girl, he finds she has been murdered. As the investigation goes along, they discover that 'Dorothy Simmons' is really Dorothy Rennick and that the man they knew as Ross may have been her husband, Albert, a car salesman with a clean record.
