Tony Dewitt, his reputation in tatters, is hired to install a newfangled telephone system in Hailey, Idaho. Racial prejudice is rampant, so Tony, who is Chinese, passing as white, conceals his ancestry. Lulu King is of mixed race and proud of it. Having seen firsthand what misery bigotry can cause, she has devoted her life to the campaigns for women's suffrage and equal rights for all. They were childhood friends, but conflicting goals drove them apart. Now fate has brought them to the same small town and the old attraction is difficult to deny. Sabotage to the telephone system and a wave of Anti-Chinese hysteria threaten Tony's career and Lulu's convictions. The consequences of their one night of love shadow their future. How long before their very lives are endangered?
