Jessie anxiously awaits a phone call, to see if her and her friend are excepted into an exclusive girl's club named the Debs.

When her friend is accepted, and Jessie's not because they don't know who she is that well, her father suggests she throw a Halloween party to impress them.

Winnie who hates Halloween, practices a magic trick on Jessie, accidentally makes her disappear (Winnie's powers get fouled up by amateurs on Halloween).

When the ""Debs"" come over, Jessie, now being partially visible eavesdrops on the Debs, and finds out they'll accept her in the group for her cool house to throw parties in, and her hunky brother Robb. Knowing this she backs out of the group, especially when she sees how they snub others not in their group.
