Maria Jackson has just moved into a new house with her recently-divorced father when she becomes aware of strange goings-on involving her reclusive neighbour, journalist Sarah Jane Smith. But things get even weirder when Maria's new friend, Kelsey, invites her on a tour of a factory which produces the mysteriously addictive energy drink Bubbleshock. There, Maria rescues a strange boy, and has nowhere to turn but to Sarah Jane herself. Together, they must discover the connection between Bubbleshock and an alien plan to conquer the Earth.
