Wallander - Firewall(2007)

Wallander: Firewall is a Swedish crime drama that plunges detective Kurt Wallander into unfamiliar digital territory. When a bloodstained taxi is discovered empty, two young girls confess to murdering the driver but refuse to reveal the body's location. The next day, a man turns up dead at an ATM, clutching a bank statement. Wallander struggles to connect the cases, but his investigation is complicated by his own deteriorating health—he experiences dizziness and disorientation that force him into hospital. As the detective grapples with both the mysteries before him and his mysterious illness, he finds himself operating in a world of computers and technology he barely understands, pushing him to the edge of his capabilities.
