Despite a full schedule, frazzled suburban single mom Jane Jeffry has agreed to lend a hand during a two-day gathering of her friend Shelley's former high school girl's club. So while the reunited ladies are dishing dirt, Jane is sweeping it up -- and she inadvertently becomes privy to all sorts of interesting postgraduate gossip and long-smoldering resentments. But then a corpse turns up among the one-time student body, the unfortunate victim of some rather nasty after-school activities. And unless Jane gets to the bottom of a sordid senior-year scandal, more alumnae are sure to die at the hands of a calculating classmate who's majoring in murder.
