Mildred Hubble is an ordinary girl whose life suddenly gets interesting when Maud Spellbody crashes her broomstick into her balcony.

Mildred wastes no time in hitching a ride to Cackle's Academy, a school for young witches, and begins her training as a new witch. But regardless of how hard she tries, her spells end up causing one disaster after another.

Based on Jill Murphy's beloved books.
