Upon her return to London, she comes across a magical looking glass and returns to the fantastical realm of Underland and her friends. There she discovers that the Mad Hatter (Johnny Depp) has lost his Muchness, so the White Queen (Anne Hathaway) sends her on a quest to borrow the Chronosphere, a metallic globe inside the chamber of the Grand Clock that powers all time. Returning to the past, she embarks on a perilous race to save the Hatter before time runs out.
