Synopsis:
Tension increases in a fashion rivalry when trendsetter Mamie Acheson is injured in a skiing accident. Rival executives were hoping Mamie would decide to endorse Maxi and Mini fashions. Due to the injury, her decision is delayed, forcing one of the rivals to resort to spying to get information.

Barbara Gordon encounters one of the spies at the library as he tries to get information from Acheson's personal designer. She follows as Batgirl. She then uncovers a plot to eliminate Mamie, but she is captured while trying to stop the crooks.
