Rivaling fictional blockbusters like "Girl on a Train" and "Gone Girl," Investigation Discovery's "Married With Secrets" looks at when happily ever after goes horribly wrong. The series dramatizes the twisted psychological warfare of marriages, telling stories of seemingly perfect unions that turn nightmarish after husbands and wives embark on secret lives that take them down devastating paths.
