Ex-CIA-black-site survivor Gibson Vaughn and two fellow fugitives hide in Portugal under the protection of criminal kingpin Baltasar Alves. When a cartel drug shipment is hijacked, they are pulled into recovering it to save their protector.
The apparent drug heist turns out to be a novel ransomware scheme, hooking the hacker protagonist. The plot fuses street crime with a cyber-extortion mechanism.
