In the role that made him a superstar, Steve McQueen plays Lt. Frank Bullitt, a hard-bitten detective assigned to protect a key witness in a Congressional investigation. When the witness is murdered, Bullitt follows a trail of lies and corruption that leads to the halls of power in Washington. McQueen performed his own stunts, including the legendary high-speed Ford Mustang chase through San Francisco—one of the most famous car chases ever filmed.
