Based on Harlan Coben's International best selling thriller, Tell No One tells the story of pediatrician Alexandre Beck who still grieves the murder of his beloved wife, Margot, eight years earlier. When two bodies are uncovered near where Margot's body was found, the police reopen the case and Alex becomes a suspect again. The mystery deepens when Alex receives an anonymous e-mail with a link to a video clip that seems to suggest Margot is somehow still alive and a message to "Tell No One".
