"Two sisters, one stubbornly cheerful (Beatrice) and one
relentlessly grumpy (Magnolia), live in a drafty old house with a
family of helpful spiders. When Beatrice is gifted magic yarn from a
giant forest spider obsessed with sustainability named Bog Myrtle,
she and the spiders set to work knitting up a perfectly warm sweater.
But greedy Magnolia sees only the opportunity for profit, and quickly
converts the old house into a magic sweater factory. The exhausted
spiders are driven to strike, and Bog Myrtle is not pleased . .
