Lisa and her young son are running away from her tyrannical husband. A house in a remote provincial village seems like the perfect place to hide. Lisa has no idea that this house was once the grave of a girl, Grace, who suffered from the abuse of her military father. These walls are witnesses to a gruesome murder, the secret of which was swallowed up by a silent lake. Liz realises that she is in danger. Because the person who committed this crime is still at large. She has no idea how close this person is and how the secret of the lake house is connected to what Liz once did. Something she will never be able to forget.
