Hollie Sanders is brutally attacked within a few weeks of finding out that she is the owner of a priceless samurai sword. Two Japanese strangers come to her rescue, and as the months pass, they assist with her recovery.

Hollie finally returns to karate training, and sets her sights on her black belt grading. Her attitude has changed during her convalescence, and she no longer allows anyone to get the better of her. She commences part-time clerical work for Harrison Devereau, a wealthy business man whose hobby happens to be collecting Japanese artifacts. When Hollie starts receiving threatening letters and phone calls, she suspects Harrison is after her sword.
