青春相对论
Teenage spy McKeyla teams up with three other super-smart girls to become secret agents who use their science and tech skills to save the day.
The girls act fast and use their skills to name a suspect when someone threatens to sabotage a state-of-the-art urban development.
A new theory emerges as the girls turn their attention to the school dance -- and having dinner at Bobby Stone's cutting-edge "smart" home.
A familiar face from McKeyla's past steps up to help as her family connections to the case grow clearer. And "Bry-ence"? Well, it's bigger than ever.
While the girls dig for more information on Bobby Stone, Adrienne and Ember make a surprising discovery about Stone Water -- and where it comes from.
The girls suit up to make a scene at the Stone Water-sponsored Young Voices Awards, where McKeyla and Kyle finally talk face to face.
