| 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. From secret sadomasochistic sex games to hit men for hire, there's no vow too sacred to break and no place too twisted to go for these spouses. And once skeletons come out of the closet, no one is safe. |
