Molly Hooper longs to be like the clique of it-girls that run Baskerville : the unaffected, unattainable Sign of Three. Unfortunately, in addition to their popularity, the Three dominate the school into submission with their cruelty. When Molly impresses the leader, Irene Adler, with her incredible forgery skills in order to get them out of detention, the Three let her into their clique. Molly is thrilled until she discovers that to be apart of the now Sign of Four, she must slouch down to their level. Meanwhile, Molly meets a mysterious new boy, Jim Moriarty. When an innocent prank results in the accidental poisoning of Irene Adler, Jim convinces Molly to stage Irene's suicide. The results are so successful that Molly and Jim, high on their newfound power, resolve to rid Baskerville of the cruelly popular elite forever.
