'Total Stranger' relates the compelling tale of a woman who lets a room and finds that she has unknowingly invited a dangerous adversary into her domain. Patti's home is no longer her castle... it has become more like a fortress with Patti blockaded in her bedroom upstairs. But it is not just the sanctity of her home that Patti has lost. She has lost her faith in the legal system. She is beginning to lose her credibility with her daughter and her boss, and if Lara, the tenant, succeeds in her plan to infect Patti with a deadly bacteria stolen from the university laboratory, Patti may soon lose her life.
