Ashley, Mona, and Beccy step out of the minivan as Mona's mom drops them off at the costume shop; hey wave Mona's mom goodbye as they enter the dusty shop. It's the evening of Halloween and to their dismay, the store only has a few costumes left that will fit them. They've been so busy with school that they didn't have time to get their costumes any sooner, but this won't stop them from having a fun time trick-or-treating. It's nearly sundown so they scurry to the teen section and find the rack has only three costumes left hanging in their plastic bags. A witch, a princess, and a cat girl.
