Asawa Ng Asawa Ko tells the story of Cristy (Jasmine Curtis-Smith), Jordan (Rayver Cruz) and their daughter Tori (Kzhoebe Nicole Baker). They’re the epitome of a happy family, but things changed when Cristy was kidnapped by the armed group KALASAG. For four years, Cristy was held captive by KALASAG.

Thinking that Cristy has died already, Jordan marries their friend Shaira (Liezel Lopez), and she becomes the mother figure for Tori.

To everyone's shock, Cristy resurfaces and tries to reclaim her old life. Will she fight for the love of her life after all that she'd been through? Can she prove that love is worth fighting for now that her daughter has wholeheartedly accepted her stepmom? Can she get Jordan back from the arms of Shaira?
