What is Safe Harbour about?

The series follows two hackers who become involved in the illegal smuggling of drugs by a criminal gang. 

The official synopsis reads: "Safe Harbor follows gifted hacker Tobias (Alfie Allen) and his ambitious best friend Marco (Martijn Lakemeier), intent on cracking into the tech billionaires club.

"Marco and Tobias are plucked from quiet obscurity and plunged headfirst into the chaos of organised crime when they cross paths with the Irish mob."

It concludes: "Leading the family's operations in Holland are Sloane (Charlie Murphy) and Farrell (Jack Gleeson) who enlist Tobias's and Marco's services to hack into the security system of Rotterdam harbour – Europe's largest shipping port – to secure undetected deliveries of drug shipments."

Is Safe Harbour based on a true story?

The series is inspired by true events, in which drug traffickers in Belgium had recruited hackers to breach IT systems in a major harbour.

Producer Femke Wolting told Variety last year that she "loved" the story and felt it could make for a "great international thriller series", prompting her to share her idea with Ozark co-creator Mark Williams. 

"Mark and I met, he loved the idea and we spent time brainstorming. That was two years and a half ago," she added.
