The city of the Golden Gate

Two English girls, Tora and Alix, go to California to escape from the pursuit of the villain. The villain, known as "Firebrand," is a gentleman by birth and education, and a gambler by profession. He follows the cousins to San Francisco, spirits Alix away to China Town, and keeps her there under opium influence with the view of inducing her to marry him. But Tora rescues the abducted girl, with the help of Gifford York, whom the girls had met in their travels. Immediately after, the earthquake causes the great fire that burned a good part of the city.
