Under Still Waters plot
"Some secrets are impossible to keep."
Together, a handsome young heiress and her not-so-successful husband make an ultimate attempt to save their marriage. On their way by car to a large family house on the lake to spend the weekend together, they run into a motorcyclist. He was standing by the road because he would run out of gas. They give him a lift to the house, but before they know it, he becomes part of their lives. And then the question arises whether the collision was an accident. After all, sometimes things are not what they seem at first glance. A good deed quickly develops into a threat.
