A widowed field mouse must move her family -- including an ailing son -- to escape a farmer's plow. Aided by a crow and a pack of superintelligent, escaped lab rats, the brave mother struggles to transplant her home to firmer ground.
The rats and mice, made intellectually superior in the original Secret of N.I.M.H., return to Thorn Valley to groom their destined leader - young Timmy Brisby.
The Wicked Queen is dead but her brother, Lord Maliss, seeks for revenge. Using the Magic Mirror to locate Snow White and the Prince, he transforms into a dragon and attacks. Maliss takes the Prince to the Realm of Doom. Snow White, with the aid of the Seven Dwarfesses, cousins of the Sevens Dwarves, must embark on a quest to save her true love.
