The phone rings. At the other end of the line is a voice from the past: Mimi. She wants Ratz to come to New York. She needs his help. Ratz was always willing to do everything for Mimi and he’s got enough problems in Vienna anyway. Maybe it’s not such a bad idea to just get away for a while. But even New York presents him a few problems: who is the old man in the basement, how true are Mimi's feelings, can you make money off a virtual murder game? And just how much does the neighbor’s dog really know?
