The series centers around the adventures of three teenage girls from Beverly Hills—Sam, Alex, and Clover—who live a double life as spies working for the World Organization of Human Protection (WOOHP).[6] The girls are recruited by the organization's leader, Jerry, to solve worsening crime conditions that arise across the globe. Their primary missions involve dealing with disgruntled and vengeful criminals who have been injured in some form during their past. Other missions have the same villains plotting revenge on the spies by ruining their personal lives. Framing each episode is a subplot that focuses on the girls' everyday lives as high school (and later university) students, dealing with relationships and their longtime high school rival Mandy. Each of the three girls has a spy suit with a heart-shaped silver belt and spy suit with different colours (red, yellow and green) and high-heeled shoes.
