Sabrina's Aunt Vesta drops by the Spellman household with a shocking announcement: After a whirlwind romance, Vesta has decided to try a life of marital bliss -- with a mortal! But Vesta hasn't told her fiance that his future wife is a licensed witch. If he finds out her supernatural secret, he might get a major case of the pre-wedding jitters. So Sabrina gives her aunt a crash course on doing chores the mortal way, using both hands instead of the point of a finger.
Meanwhile, Aunt Zelda and Aunt Hilda are planning the most normal nuptials ever -- they hope -- to fool the groom and his mortal friends, even though they doubt their impulsive sister will actually make it to the altar.
But pretending to be mortal isn't Vesta's only problem. She's afraid that an old curse on the Spellman family will doom her to be unlucky in love. Now, Sabrina's on a quest to save true love -- but will a magic-less Aunt Vesta make it to her own honeymoon?
