A note left for you in your San Francisco hotel states that unless you deliver a ransom to a specified location you will never see your wife again. At this point life becomes even more complicated as an earthquake reduces your hotel to rubble.
Notes
The Atari version was published by Adventure International (USA) in 1981. This can be identified by the "San Francisco 1906" title and 1981 copyright date on the title screen, and the abbreviated room descriptions. It was then published by Adventure International (UK) in 1982. This can be identified by the "Earthquake 1906" title and 1982 copyright date on the title screen, and the slightly longer room descriptions. After Adventure International went bust, the original version was published by Prism Leisure under the 'A1' label in 1986.
