Scammers scheme to defraud a pensioner out of his life's savings. They pretend to be setting up an app, so that Sean Casey can check his own credit card transactions at any time. The "scammers" lie and cheat, using nefarious methods to access his personal bank account. But what they don't know, is that Sean himself has a BSc in computer forensics and he's being setting them up for the fall. Not only do the "scammers" fail to steal Sean's money, but he 'hacks' them instead and uploads a virus to wipe out their computer's software.
