A freak accident at a chemical plant in France contaminates hundreds of tons of solvent, some of which is already in use in injection vials to treat millions of patients throughout Europe. Lilliana Fulciniti and Lewis Davies are the company scientists responsible for solving the problem - or covering it up. Solitary complicated characters, each with a personal burden tormenting their short lives, the crisis draws them to each other like lost souls in a storm. They alone understand the enormous risk to human life the contamination poses, as they fight to avoid the inevitable tragedy. Their love grows as they wrestle with corrupt company leaders, a suspicious media and their own consciences. Only they can avert the disastrous outcome of the lethal dose.
