Since I voluntarily left the Lockwood Agency, a lot of things have changed in my life. Well, firstly, I began to work as a freelancer, secondly, I almost got killed, and my ghostly friend - a skull in a jar - was kidnapped. And I had to ask for help from old friends . The investigation led us to the black market, where they traded stolen Sources with dangerous and rare ghosts imprisoned in them. And my skull was very much to their taste .. But as always, a small discovery pulls a large one, unraveling the tangle of crimes. It seems that now we are close to solving the problem the invasion of ghosts on England. But the truth is too dangerous, especially if two fearless agents, which Lockwood and I are, dare to look beyond the line - into the world of ghosts.
