Sophie Anderson never recovered from the tragedy that shattered her childhood when, at the age of eight, she had an unbearable vision in her sleep of her little brother's murder.

So, when Sam Wright, her colleague and best friend, asks her to participate in the investigation, she is ready to do anything to help her. But Sam disappears in turn, and Sophie feels her heart freeze: this time, it's Sam herself she saw in the killer's hands…
