Jane makes a friend out of Mr. Collins Pendleton a kindly old man who was also friends with Greg in highschool. After an argument with Greg about her refusal to move in with him, her tiles on her kitchen floor are smashed by her neighbor from downstairs and she calls the police. Furious, she gets her own back by making more noise. The next morning she falls down the stairs by tripping on a stair smeared with grease. She then tries to make amends by sending her neighbor a sorry note asking for a truce.However things get worse as Janes bathtub and apartment are infested with maggots and mice and she calls an exterminator Costanzo to handle the problem. She then finds out from a Korean grocer that Alice, the neighbor right beneath her, had suddenly stopped ordering her daily groceries. When she tries to tell Martha this, Martha turns against her, saying she has no respect for privacy or authority and that shes toeing the line by calling the police and talking to the Koreans. After the exterminator reveals that the mice infestation was no accident and that most likely her neighbor had been putting them through a drilled hole in her floor, Jane becomes terrified. She decides to break into the 4th floor to take pictures and gather evidence. There she finds mice and rats in cages, a typewriter and the ceiling completely mapped out with her furniture, along with word Portcullis written on a wall. ........
