"Some of his secrets may be worth killing for," is not the best epiphany to have when you're grieving your husband's sudden homicide, but that is how Alison Whitford's world falls apart in Lifetime's upcoming thriller 'All My Husband's Wives'. With a sensational name like that, the film sounds like a murderous, dark spin on the 2014 movie 'The Other Woman', where Kate's (Leslie Mann) perfect marriage falls apart when she finds out of her husband's (Nikolaj Coster-Waldau) two other mistresses, played by Cameron Diaz and Kate Upton. Alison is more of your Cameron Diaz's workaholic, no time for relationship character, but her realization unfurls ever darker secrets to make for a meaty suspense thriller. Here's all you need to know about the movie!

When it’s revealed that he was murdered even more secrets about his life come to light. It soon becomes clear that Alison was not the only one mourning Dominick, and that his death was only the beginning of a larger plan. Perhaps her perfect husband wasn’t so perfect after all, and some of his secrets may be worth killing for."
