Alice is appointed to save her beloved Mad Hatter from deadly grief by traveling back to the past, but this means fatally harming Time himself, the noble clockwork man with the device needed to save the Hatter's family from the Red Queen.
 
A forced sequel you can tell no one asked for including the returning actors.
 
FUN FACT:  The character of Time does not appear in either of Lewis Carroll's two Alice books, but is mentioned in Alice's Adventures in Wonderland, Chapter 7. The Mad Hatter tells Alice that he had quarreled with Time, and in fact had been sentenced to death for murdering time. Ever since then, time cursed The Mad Hatter so that "it's always tea-time, and we've no time to wash the things between whiles." This is nodded to in this film, when Time, after crash-landing, traps the Mad Hatter, the Dormouse, and the March Hare in a specific time to keep them from hindering him.
