Ambitious politician Walter Chalmers (Robert Vaughn), is holding a Senate subcommittee hearing in San Francisco on Organized Crime in America. Hoping that by bringing down mobster Pete Ross (Vic Tayback) with the aid of key witness Johnny Ross, Pete’s brother, Chalmers’ political standing might improve. The story takes place the weekend before the hearing, from Friday night (during the opening credits) to Sunday night.
Following the theft of $2,000,000, and his escape to San Francisco, Johnny (actually Albert Renick) (played by Felice Orlandi) is placed in the San Francisco Police Department’s protective custody for the weekend. Chalmers requests Lieutenant Frank Bullitt’s (Steve McQueen) unit to guard him.
Bullitt, Sergeant Delgetti (Don Gordon) and Detective Carl Stanton (Justin Tarr), give Ross around-the-clock protection at the Hotel Daniels, a cheap flophouse near the Embarcadero Freeway. Before Ross enters the hotel, he makes several phone calls. Late Saturday night, while Stanton is guarding him, the desk clerk calls and says Chalmers and a friend are seeking Ross. Stanton calls Bullitt, who tells him not to let them in, as Chalmers would not show up at 1:00 in the morning. Meanwhile, Ross takes the security chain off the door. Suddenly, a pair of hitmen, Mike (Paul Genge) and Phil (played by stunt driver Bill Hickman), burst into the room and shoot both Inspector Stanton and Ross, seriously wounding them both.
Bullitt returns home to find Cathy asleep. He enters the bathroom to wash his hands and looks into the mirror, quietly contemplating his future. The final shot lingers on Bullitt’s gun and bullets.
