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?
