Here's b-roll of people preparing for a house party at a mansion in San Francisco's wealthy neighborhood, Pacific Heights. The party was being thrown by Melvin Belli, a prominent local lawyer. 

Two valets, a black man and white woman, both wearing white work coats, stand by an idling sports car on a street filled with parked cars. The woman valet parks the car. The driver of the sports car, who could be a man or a woman, crosses the street; the driver is wearing a tuxedo with a red bowtie and ruffled shirt.

A line of cars travel down a residential road. The black male valet directs a silver Porsche to park at a specific point on the street. A middle-aged couple gets out of the Porsche. The valet places a parking stub under one of the Porsche's windshield wipers; the valet then hands the corresponding stub to the Porsche’s driver. The black valet then enters the Porsche, likely to park the vehicle until the couple returns. 

We see bumper-to-bumper traffic down a two-way street. A man in a white sports coat leans out of a car window and waves excitedly at the camera.

The dome of the Palace of Fine Arts and the nearby surrounding neighborhood is seen in the far distance, likely from the vantage point of a home in Pacific Heights.

We see an elegant, two-story, greenish-beige home with decorative moldings above the bottom-floor windows. The home is surrounded by shrubs, trees, and leafy plants that are planted around it and a low wall. 

A black security guard wearing a jacket and badge opens a gate for a man in a teal shirt who is carrying a stack of boxes. The man in teal is likely a delivery person or a waiter for the party. A two-story brick mansion is seen in the background.

The black security guard lets the man in teal inside the gate again. The guard then lets a woman wearing a red dress and black blazer inside the gate and accompanies her to the mansion. 

Next, we see a lavish courtyard where a large table is covered by a white tablecloth. Shrubs and plants decorate the courtyard.

A man in a gray suit -- perhaps he is a host or in charge of the party’s waiters -- opens a packet of spoons and empties the packet onto a small table. The table has two large bowls of oysters beside dipping sauces. We see a close-up of a bowl of oysters sitting on ice and covered with ice.

Two tables are filled with beverages, glasses, and carafes -- all nicely arranged. A dirty-blond haired man, likely a waiter, who is wearing a ruffled tuxedo shirt, moves boxes.

From within the courtyard, which is colored a light peach, we see the windows on the mansion’s second floor. The camera then pans down from the windows back to the courtyard showing its columns and gated doorway. A waiter in a tuxedo shirt carries a brown sack on his right shoulder, walking away from the camera. 

In the clip's final scene, a woman in a dark dress, white gloves, and a lace shawl enters the mansion's courtyard through the gated doorway. She is accompanied by two men wearing tuxedos; one of the men has a mustache, the other is wearing a red bowtie and red sash. The trio walk screen left down a covered patio area.
