 While in a toy shop in Chinatown, San Francisco Kelly and Scott meet an attractive Chinese young woman named Mai Lin. Kelly is immediately attracted to her and strikes up a conversation. While showing her the sights they find it strange that she says she is from San Francisco yet has no knowledge of the most obvious San Franciscan sights...Alcatraz, Golden Gate Bridge, etc. The mystery gets deeper when they are assaulted and she is stolen away. Their investigation leads them to an ancient Chinese cult who have plans for Mai Lin.
