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.
