Meanwhile, her boss postpones publishing her breakthrough findings and assigns her to investigate a peculiar sample of bacteria instead. Her initial resentment soon disperses as she grows intrigued by this new challenge.
But when she uncovers a shocking secret that threatens the lives of millions, her very survival is all of a sudden hanging by a thread, and she needs to escape—with unexpected help from her new neighbour.
