Maria finds herself taken back in time by the alien Graske to a pier in 1964, as the drama series continues. There, she meets a young girl her own age called Sarah Jane Smith who, with her friend Andrea, is about to embark on a fateful adventure.

Taken by the Graske again, Maria is then reunited with the present-day Sarah Jane but, with them both trapped in limbo as part of the meddlesome Trickster's plan to wreak chaos, they are helpless to stop the huge meteor which is about to crash into the Earth.

Alan, Maria's dad, is the only one able to remember Sarah Jane and Maria and faces a struggle to bring them back in time to save the world.
