But no matter how much she tries to push her fears aside, she can’t because she took that photo. On their honeymoon. She just can’t let it go. Suddenly other signs of betrayal begin to add up and so Charlie does the only thing she can think of to defend her position – she signs up to the app to catch Oliver in the act. But Charlie soon discovers that infidelity is the least of her problems. Nothing is as it seems and nobody is who she thinks they are ...
