One day, I watched this movie just because there was nothing else on TV. While I was watching, something weird happened and it actually appealed to me.
The plot concerns Mary Margaret Dennis (Jamie Renée Smith), whose imaginary friends Bella and Donna tell her to make a sculpture of principal Miss Mallard (Eileen T'Kaye). Meanwhile, her mother Sylvia (Saxon Trainor) is experimenting with opening doors into other universes with a machine called the Doppelgänger (what a silly name). She succeed and asks her colleague Laszlo Tuttel to her place for dinner to celebrate.
Meanwhile, Mary Margaret has gotten into her great grandfather MArgaret's book of flowers and discovers one with strange berries that she takes into her room. Something weird happens and Bella and Donna disappear through Mary Margaret's newly-acquired hand-me-down mirror.
At dinner, MAry Margaret gets into trouble when Bella and DOnna throw tea on Mrs Tuttel (how could they do that if they are supposed to be on the other side of a mirror?). She is sent to her room and discovers that there is a new world behind her mirror (thorugh the mirror berries mshe discovered earlier. There she meets lazy Mirrorminder Tansy, and Mirror Master Melilot.
She also attracts the attentions of the tea-obsessed Drakes, ruled by the evil queen Dragora, who want her because people make the best tea (they get steamed in boiling water for a minute). And she is out for the berries.
