Janine takes the day off to take Egon to visit her family, only for them to be called back to headquarters after Slimer inadvertently activates a dimensional gate machine created by Egon, which allows a group of miniature demons to pass into the real world. Things take a turn for the worst when the demons combine to make one giant demon and it runs amok throughout New York. Meanwhile, Janine and Louise (Janine's temporary cover), along with Slimer, are left at HQ to battle against a trio of spirits who have passed through the dimensional gate after Louise activates the machine for a second time.
