Anna and Erik's marriage seems ordinary, until Anna begins receiving disturbing messages from a stranger who knows her every move. What starts as unsettling quickly spirals into obsession, manipulation, and danger. Hans Koppel's psychological thriller is a chilling exploration of control, fear, and the terrifying consequences of being watched.
