At Miss Twirl's Ballet Studio, a young girl named Erin practices her dance routines alongside her best friend, Paul. One day, she spots a tiny spider in the corner of the practice room. Spiders usually frighten her, but this one catches her attention. It seems to be copying her movements! As Erin watches in wonder as the spider gracefully twirls around, she discovers an unlikely friendship. When a pest control company threatens to spray the studio, Erin must find a way to protect her eight-legged dancing partner by showing everyone that spiders aren't just harmless, they're also nature's own pest control experts.
