Count Freeze gets permission from Prime Evil to set a trap for the Ghostbusters in Blackstone Castle, but Prime Evil knows the real reason he wants to use the castle is to search for the wizard who lives there. Eddie convinces the others to leave him in charge of the office for one night and Freeze lures him into a trap, and the other Ghostbusters are soon trapped too. Prime Evil comes to collect the Ghostbusters and defeats Count Freeze, but Eddie escapes in the battle. He meets the wizard, who agrees to use his magic to make Eddie smarter than Jake and stronger than Tracy so he won't mess up anymore, but warns Eddie he can't tell anyone who he really is. With his new abilities Eddie easily saves his friends and defeats all the ghosts, but when he sees how worried his friends are even though he messed up before, Eddie realizes he doesn't want to be a superhero if it means giving up his friends.
