Dario Argento's The Card Player is the 2004 Italian horror mystery from fright master extraordinaire Dario Argento (Suspiria, Tenebre, Deep Red, Phenomena). The story concerns a police woman named Anna Mari (Stefania Rocca), who one day on the police computer is challenged by an online chatter to a game of poker. If she does not play this person he will kill a victim he has taken hostage and if Anna, doesn't win the victim will be killed as well. The victims are broadcast on the internet to Anna, through a web camera. Anna teams up with a British agent to catch this killer and they try and trace the internet connection to find out where the person is using the internet from. But they have to keep them on the computer long enough to track him so they get a young poker whiz to challenge the killer and they play a cat and mouse game to catch them.
