From NetFlix:

This thriller directed by James Foley stars Halle Berry as Ro, a woman who risks her life to discover the identity of a stranger lurking on the Internet who might hold the answers to her friend’s murder. As Ro digs deeper, she discovers a murky world of online deception peopled by the likes of Harrison Hill (Bruce Willis), a mysterious figure who could either be a friend or a foe. Giovanni Ribisi, Leigh Spofford and Jason Antoon also star

If you look up Giovanni Ribisi in IMDB you will find he has appeared in at least 80 productions. For me he stands out in this film as the most interesting character. He often plays a dark role.

Bruce Willis, I am happy to say, in this case succeeds by playing Bruce Willis. His collisions with Halle Berry are clever and tense.

Tell me if you guessed the surprise ending. Also pay attention to the last few seconds of the film and tell me what is going on (hint: “look through the window”).
