Two stories feature scheming wives incapable of telling the truth. First, Navy man Cory Voss and his wife Catherina "Cat" Voss are a young couple raising two children in Newport News, Virginia. Despite Cory's love and devotion, Cat secretly falls for another man. But betraying her marriage vows is just one angle in Cat's complicated web of lies, and eventually she seeks a more permanent solution to finally end her marriage. Then, Barbara Garcia and her husband Cipriano, are retirees living in Hobart, Indiana. After sharing more than four-decades of marriage, the seniors have weathered most of life's ups and downs together. But when Cipriano is found dead in another state, Barbara becomes a suspect, and investigators learn she has many different versions about what may--or may not--have happened to her husband.
