 Sidelined for five years since their spectacular save (an near destruction) of New York City, the superstars of the supernatural spring back into action when the infant son of single-mother Dana Barrett (Sigourney Weaver) becomes the target of a powerful demonic force. Reunited with the no-nonsense Zeddemore (Ernie Hudson), nerdy near-sighted Louis (Rick Moranis) and their ever-industrious secretary Janine (Annie Potts), the heroes of the hereafter must put a stop to an enormous underground river of slime ready to rot the roots of the entire Big Apple. Now, if your hometown was on the verge of being sucked down into the 10th level of Hell, who else would you call?
