The series follows gifted hacker Tobias (Allen) and his ambitious best friend Marco (Lakemeier), who are intent on cracking into the tech billionaires club. They are plucked from quiet obscurity and plunged headfirst into the chaos of organised crime when they cross paths with the Irish mob. Leading the family’s operations in Holland are Sloane (Murphy) and her brother Farrell (Gleeson), who enlist their services to hack into the security system of Rotterdam harbour — Europe’s largest shipping port — to secure the undetected deliveries of drug shipments.
